* termhooks.h: Declare and document them.

BSD/GNU regexp to insist that line number end with a colon or
close-paren.

shouldn't change the buffer text. Make it not. If we're in the
blank space before another comment, fill that one as a comment,
not as normal text.
* c-mode.el (c-fill-paragraph): When guessing the fill prefix,
don't ever grab any actual text.
from thinking it's a CSH script. Most systems will just use
/bin/sh to run it, which is what we're expecting; the only other
shells which might try to interpret it themselves are probably
Bourne-compatible.
now. Change references.
* Makefile.in: Adjust `install.mumble' targets to install
`src/emacs', not `src/xemacs'.
* Makefile.in (install, install.sysv, install.xenix, install.aix):
Don't try to copy the info files if there aren't any; the
unexpanded globbing pattern disappoints `install'. Ignore the
return status of that command.
(tags-table-list): Elt of nil is not special.
(tags-expand-table-name): Value of nil is not special.
(tags-next-table): Removed arg RESET; no caller used it.
(visit-tags-table-buffer): Don't need to do tags-expand-table-name in or form.
When table is invalid, only set tags-file-name to nil globally if its
global value contained the losing table file name.
(find-tag-tag): Return a string, not a list.
(find-tag-noselect, find-tag, find-tag-other-window, find-tag-other-frame):
Changed callers.
(etags-recognize-tags-table): Call etags-verify-tags-table, rather than
duplicating its functionality.
(visit-tags-table-buffer): When CONT is 'same, set it to nil after the
cond. We want the normal list frobbing to take place in this case.
(find-tag-other-window): Save and restore window-point around call to
find-tag-noselect.
may want to edit the values of the path variables.
Make path specification conform to GNU coding standards.
* configure (long_usage): Remove all traces of old arguments from
usage messages, and document the options we do accept in more
detail: -with-x... and --srcdir.
(options, boolean_opts): Deleted; we don't have enough options to
make this worthwhile.
(prefix, bindir, lisppath, datadir, libdir, lockdir): Deleted,
along with the code which supported them; these should be set as
arguments to the top-level make.
(config_h_opts): Since this no longer doubles as a list of option
names, make them upper case; this simplifies the code which uses
them to build the sed command to edit src/config.h. Change the
code which sets them.
(cc, g, O): Don't allow the user to set these using options; they
should be specified using `CC=' and `CFLAGS=' arguments to the
top-level make. Just choose reasonable default values for them,
and edit them into Makefile.in's default CC and CONFIG_CFLAGS
values.
(gnu_malloc, rel_alloc): Don't allow the user to set these using
options; use them whenever the configuration files say they're
possible.
Simplify the argument processing loop. Don't accept abbreviations
for option names; these might conflict with other configuration
options in the future.
Add some support for the `--srcdir' option. Check for the sources
in . and .. if `--srcdir' is omitted. If the directories we will
compile in don't exist yet, create them under the current directory.
Note that the rest of the build process doesn't really support
this.
Edit only the top Makefile. That should edit the others. Edit
into the makefile: `version', from lisp/version.el, `configname'
and `srcdir' from the configuration arguments, `CC' and
`CONFIG_CFLAGS' as guessed from the presence or absence of GCC in
the user's path, and LOADLIBES as gleaned from the system
description files.
Simplify the report generated; it doesn't need to include any
description of paths now.
Make `config.status' exec configure instead of just calling it, so
there's no harm in overwriting `config.status'.
* Makefile.in (version, configname): New variables, used to choose
the default values for datadir and libdir.
Path variables rearranged into two clearer groups:
- In the first group are the variables specified by the GNU coding
standards (prefix, bindir, datadir, statedir, libdir, mandir,
manext, infodir, and srcdir).
- In the second are the variables actually used for Emacs's paths
(lispdir, locallisppath, lisppath, buildlisppath, etcdir, lockdir,
archlibdir), which depend on the first category.
datadir and libdir default to directories under
${prefix}/lib/emacs instead of ${prefix}/emacs, by popular
demand.
etcdir and lispdir default to subdirectories of datadir.
archlibdir defaults to libdir.
The new installation tree is a bit deeper than it used to be, so
use the new make-path program in lib-src to build them all.
Always build a new src/paths.h.tmp and then move-if-change it to
src/paths.h, to avoid unnecessary rebuilds while responding to the
right changes.
Remove all mention of arch-lib. Run utility commands from
lib-src, and let the executables be copied into archlibdir when
Emacs is installed.
Add targets for src/Makefile, lib-src/Makefile, and
oldXMenu/Makefile, editing the values of the path variables into
them.
Let lib-src do its own installation.
(datadir): Default to putting data files under
${prefix}/lib/emacs/${version}, not /usr/local/emacs.
(emacsdir): Variable deleted; it would only be confusing to use.
(lispdir, etcdir): Default to ${datadir}/lisp.
(mkdir): Use make-path for this.
(lockdir): Do this in mkdir.
(Makefile): New target.
* configure (usage_message): Rename to long_usage.

under both `emacs' and `emacs-VERSION'.
* Makefile.in: Doc fix.
* Makefile.in (exec_prefix): New variable, as per latest version
of coding standards.
(bindir, libdir): Use it, instead of `prefix'.
(lib-src/Makefile): Edit value of exec_prefix into lib-src/Makefile.
* Makefile.in (mandir): Make the default value for this depend on
$(prefix).
* Makefile.in (datadir, statedir, libdir): Make these all default
to ${prefix}/lib.
(lispdir, locallisppath, etcdir, lockdir, archlibdir): Adjusted
to compensate.
* Makefile.in (install, install.sysv, install.xenix, install.aix):
Install the etags and ctags man pages too.
* Makefile.in (distclean): Don't delete backup files; that's the
job of extraclean.
(extraclean): Like distclean, but deletes backup and autosave files.
Make path specification conform to GNU coding standards.
* configure (long_usage): Remove all traces of old arguments from
