bug#39902: 28.0.50; Marking in dired with active region

[Michael Heerdegen]

Hello,

(1) Docstring of `dired-mark' says

  "If the region is active, mark all files in the region."

However, the file in the last line of the region is never marked, even
if the region spans the whole line of this file.  I find that behavior
wrong and contradicting the docstring.  But it seems it has been like
that for a long time (forever?).  Nevertheless, I'm always confused by
that behavior.

(2) Most of the time I rather want `dired-mark-files-regexp' to respect
an active region - but that isn't implemented (though it would not be
hard to do).  I think that would be useful.

(3) I didn't check if more dired (un)marking commands should be treated
or could be enhanced.  How the region is interpreted (see (1)) should be
kept consistent.


Thanks in advance,

Michael.
