Subject: bug#63875: 26.3; Doc of `dired-guess-shell-alist-user'
Date: Sat, 3 Jun 2023 16:08:11 +0000

The doc string doesn't say what REGEXP is, e.g., what it's intended to
match.  It should say that up front and explicitly.

Manual (dired-x) `Shell Command Guessing' sort of says it, if you read
carefully and guess a bit.

Please say explicitly that REGEXP is a regexp that's used to match file
names.  And say how the alist entries are used.  All that's said, so
far, is that this is a "User-defined alist of rules for suggested
commands."

Rules used how?  What does matching file names have to do with using a
command?  Again, the manual does say this somewhat, but not the doc
string.

The doc refers to `dired-guess-shell-alist-default', but the doc for
that variable doesn't explain anything, so it doesn't help with the
missing info for `dired-guess-shell-alist-user'.

FWIW, the comment in file dired-x.el that introduces these variables
describes them better than the doc in some ways: what they're for, how
they're used.
