- Implement traversal of subdirectories found in
`dired-rmjunk-patterns'. If any of the directory components of any
of the patterns in `dired-rmjunk-patterns' exist in the current
working directory, they will be optionally traversed. For example:
if `dired-rmjunk' is invoked from the user's home directory, and
".local/share/recently-used.xbel" is a member of
`dired-rmjunk-patterns', subdirectory traversal would open a new
dired buffer at "~/.local/share/" and mark junk files for deletion.
Invoking `dired-do-flagged-delete' will cause the next candidate
subdirectory to be traversed. Subdirectories containing no junk
files are skipped.
