`dired-omit-mode' matches file names against regexps, and removes their
lines from the Dired listing.
It can also be useful to match other things on a file's line, besides
its name. For example, match the `x' permission to omit executable files.
The attached code implements this. It adds a new option,
`dired-omit-line-regexp', which is a regexp to match lines.
It redefines `dired-omit-mode', `dired-omit-expunge', and
`dired-do-kill-lines'. It adds optional args LINEP and INIT-COUNT to
`dired-omit-expunge', and optional arg INIT-COUNT to
`dired-do-kill-lines'.
When the new option is non-nil, `dired-omit-mode' calls
`dired-omit-expunge' a second time, to omit matching lines.
The updated doc of `dired-do-kill-lines' speaks only of removing lines
from the listing, not of "killing" lines, to avoid confusion with kills
(the `kill-ring' is unaffected by this command). We should consider
renaming the command altogether, but then the key binding of `k' would
no longer be mnemonic'. At the very least, if the doc continues to
speak of "killing" lines then it should explicitly say that the
`kill-ring' is unaffected.
If this improvement is OK (try it) then I can send a patch. Otherwise,
I won't bother.
The improvement was inspired by this user question:
