(set_point_both): Use `adjust_for_invis_intang' to do most of the work
for dealing with invisible+intangible regions. Do so before and after
both forward and backward movements, to handle both front-sticky and
rear-sticky cases.
thumb (based on an ad-hoc estimate of 30 chars per line) to avoid
annoying flicker.
(xm_scroll_callback): Get rid of the now unnecessary kludge.
(XTread_socket): Mark it static.
Add fortran-comment-line-start-skip to comment-start-skip.
(fortran-comment-indent): Keep whole-line comments in column 0.
(fortran-find-comment-start-skip): New arg `all'.
If ALL is nil, make sure we only match comment-start-skip if we
can't match fortran-comment-line-start-skip.
Fix bug that made it return t but without moving point when
matching '!'! (a false-comment followed by a real comment).
(fortran-indent-comment): Use new `all' argument above.
Be careful not to add an incorrect comment-starter like "C"
in comment-column.
(fortran-split-line): When splitting a comment, reuse the comment
starter from the current line rather than fortran-comment-line-start.
(fortran-indent-line, fortran-auto-fill): Simplify thanks to the
cleaner behavior of fortran-find-comment-start-skip.
(fortran-fill): Don't be confused by ! inside a comment.
(fortran-break-line): Minor cleanup and simplification.
(lisp-loop-forms-indentation, lisp-simple-loop-indentation): New
user options.
(extended-loop-p, common-lisp-loop-part-indentation): New
functions.
(common-lisp-indent-function-1): Renamed from
common-lisp-indent-function.
(common-lisp-indent-function): Handle loop forms specially.
(lisp-indent-defmethod): Use car/cdr instead of first/rest.
(Python_functions, PHP_functions): Name tags, for ctags' sake.
(TeX_commands): Name tags. Correction of old disabled code.
* etags.c (curfiledir, curtagfname): New global variables.
(process_file): Initialise them.
(readline): Canonicalize the name found in #line directive.
