SZEDER Gábor dd160d794f bash prompt: faster untracked status indicator with untracked directories
If the untracked status indicator is enabled, __git_ps1() looks for
untracked files by running 'git ls-files'.  This can be perceptibly slow
in case of an untracked directory containing lot of files, because it
lists all files found in the untracked directory only to be redirected
into /dev/null right away (this is the actual command run by __git_ps1()):

  $ ls untracked-dir/ |wc -l
  100000
  $ time git ls-files --others --exclude-standard --error-unmatch \
    -- ':/*' >/dev/null 2>/dev/null

  real	0m0.955s
  user	0m0.936s
  sys	0m0.016s

Eliminate this delay by additionally passing the '--directory
--no-empty-directory' options to 'git ls-files' to show only the name of
non-empty untracked directories instead of all their content:

  $ time git ls-files --others --exclude-standard --directory \
    --no-empty-directory --error-unmatch -- ':/*' >/dev/null 2>/dev/null

  real	0m0.010s
  user	0m0.008s
  sys	0m0.000s

This follows suit of ea95c7b8f5 (completion: improve untracked directory
filtering for filename completion, 2013-09-18).
