I propose the following changes to two docstrings in locate.el.  The
most important one is the expansion of the mode documentation.  The
change to `locate-prompt-for-command' is necessary because the first
line is (much) wider than the maximum allowed 67 characters.

If there are no objections, I will install within a few days.

This is the first in a series of three patches to locate.el,
find-dired.el and dired-aux.el.

They correct a variety of malfunctionings, bugs and misfeatures
regarding inserted subdirectories in *Locate* and *Find* buffers as
well as in ordinary Dired buffers.  The patches to locate.el and
find-dired.el are just updated versions of patches I submitted
earlier.  But to function well, they need the changes in dired-aux,
which I will post separately.

The patches to locate.el and find.el do not fix every single problem
in  *Locate* and *Find* buffers.  That is impossible, because both are
in a form that Dired is not 100 percent prepared to cope with.

I will install all three patches within a few days if there are no
objections.

Below is my latest and probably final patch for locate.el.

The main visible changes is that the header now looks like:

  /:
 Matches for compdir:

Having `  /:' as first line is absolutely necessary when having
inserted subdirectories.  Otherwise, dired-subdir-alist can get
corrupted and then things _really_ go wrong.

The patch below also corrects a problem unrelated to subdirectories.
Currently, locate.el has _two_ `;;; Commentary' sections.  This does
not work.  Currently the only documentation one gets by following
links after `C-h p' are some MS Windows specific technical details,
whereas the more general stuff gets ignored.  I hardly believe that
this is intentional.  The patch below combines both `Commentary'
sections into one and puts the OS specific stuff at the end.

I will finally commit after waiting still a while to see if there are
any objections to the final version.

  In that buffer, you can use almost all the usual dired bindings.
  \\[locate-find-directory] visits the directory of the file on the current line.
  
+ As usual, you can insert subdirectories using \
+ \\[dired-maybe-insert-subdir] and update them
+ using \
+ \\[dired-do-redisplay].  However, \\[dired-do-redisplay]. only works on \
+ subdirectory header lines.
+ At other places, it may cause strange results.  These can be undone
+ using \\[dired-undo].  Specific `locate-mode' commands, such as \
+ \\[locate-find-directory],
+ do not work in subdirectories.  Reverting the buffer using
+ \\[revert-buffer] deletes all inserted subdirectories.
+ 
+ Operating on listed files works, but does not always
+ automatically update the buffer as in ordinary Dired.
+ This is true both for the main listing and for subdirectories.

I forgot to say that the patch to locate.el requires updates to
related patches for dired.el and dired-aux.el which I am submitting to
emacs-devel separately.

Sincerely,

Luc.
