the file's time-stamp is replaced by its MD5 checksum.
(autoload-generate-file-autoloads): Use MD5 checksum instead of
time-stamp for secondary autoloads files.
(update-directory-autoloads): Remove duplicate entries.
Use time-less-p for time-stamps, as done in autoload-find-destination.
for file-local settings.
(autoload-generate-file-autoloads): Add `outfile' arg.
(update-directory-autoloads): Use it to directly call
autoload-generate-file-autoloads instead of going through
update-file-autoloads so we avoid redundant searches and so we can know
the set of buffers changed so we can save them all.
rather than throwing `up-to-date'.
(autoload-generate-file-autoloads): Adjust correspondingly.
(update-file-autoloads): Be careful to let-bind
autoload-modified-buffers and adjust to new calling conventions.
(autoload-modified-buffers): Make it a dynamically scoped var.
(update-directory-autoloads): Use file-relative-name instead of
autoload-trim-file-name.
(autoload-insert-section-header): Don't use autoload-trim-file-name
since the file is already relative now.
(autoload-trim-file-name): Remove.
(autoload-generate-file-autoloads): New function extracted from
generate-file-autoloads. Use file-relative-name. Delay computation of
output-start to the first cookie. Remove done-any, replaced by
output-start.
(generate-file-autoloads): Use it.
(autoload-find-destination): Make use of `begin' var.
(update-file-autoloads, update-directory-autoloads): Use it.
(autoload-file-load-name): New function.
(generate-file-autoloads, update-file-autoloads): Use it.
(autoload-find-file): Accept non-absolute argument. Set default-dir.
(generate-file-autoloads): If the autoloaded form is malformed,
indicate the problem with a warning instead of aborting.
(generate-file-autoloads): Obey it. Return whether autoloads were
added at point or not.
(update-file-autoloads): Use this new return value.
Remove redundant test for the presence of an autoload cookie.
(autoload-before-p, autoload-remove-section): New functions.
(generate-file-autoloads): Use them.
(update-file-autoloads): Use them. Return FILE if there's no cookie.
Make sure the autoload file is properly formatted when creating it.
(update-autoloads-from-directories): Use them as well.
Only update autoloads for files whose timestamp has changed.
Add a dummy entry to remember the files which had no autoload cookies.
