for backward compatibility with packages that bind it during
`find-image'. Suggested by Katsumi Yamaoka.
(image-search-load-path): Handle symbols whose values are strings.
put appropriate overlays over underscore characters.
(glasses-convert-to-unreadable): If glasses-separator differs from
underscore, try to convert glasses-separator characters to underscores.
Use with-current-buffer.
(ange-ftp-gwp-start): Remove unused var `gw-user'.
(ange-ftp-guess-hash-mark-size): Remove unused var `result'.
(ange-ftp-insert-directory): Remove unused var `short'.
(ange-ftp-file-name-sans-versions): Remove unused var `host-type'.
(hs-allow-nesting): New user var.
(hs-discard-overlays): Skip "internal" overlays if nesting allowed.
(hs-hide-block-at-point): When nesting allowed,
if there is already an overlay in place, delete it.
(hs-safety-is-job-n): Delete func; remove call sites.
(hs-hide-level-recursive): Don't pre-clean if nesting allowed.
(hs-overlay-at): New func.
(hs-already-hidden-p, hs-show-block): Use it.
(hs-hide-all): Don't pre-clean if nesting allowed.
(hs-show-all): Temporarily disallow
nesting around call to `hs-discard-overlays'.
* mail/sendmail.el (mail): Use new buffer if `noerase' is `new'.
Fix behavior if noerase is `t' and there is no mail buffer.
* simple.el (sendmail-user-agent-compose): Use a new mail buffer
if `continue' is nil, rather than signal an error.
until the user actually tries to go there.
(compilation-next-error-function):
Pass compilation-find-file the directory from the file-struct.
(compilation-internal-error-properties): Separate local FILE-STRUCT
from FILE. Doc the args better. Rename arg FMT to FMTS.
(compilation-find-file): Arg DIR renamed to DIRECTORY.
Expand it, and if nil, use default-directory.
(compilation-get-file-structure): Don't mix specified directory
with default directory. Put specified directory into
file-struct. Don't make the file name absolute.
(compilation-error-regexp-alist): Doc fix.
(compile-command): Add autoload.
(compilation-disable-input): Add autoload.
(woman-topic-at-point): Renamed to woman-use-topic-at-point.
(woman-file-name): Reflect renames above. Automatically use the
word at point as topic if woman-use-topic-at-point is non-nil.
Otherwise offer it as default but don't insert it in the
minibuffer. Also use `test-completion' instead of `assoc' as
suggested by Stefan Monnier.
