[0/2] Print stash info in the v2 porcelain format

Message

When --porcelain=v2 is given --show-stash is silently ignored. But the
format is useful for quick gathering of repo status, for e.g. prompts.
And indeed git's own git-prompt.sh supports printing a sigil when stash
entries exist.

The first patch is just a very small refactoring. It's far from
necessary (although as it stands the second patch depends on it) but it
makes sense to me. The second patch is the one that counts.

Øystein Walle (2):
  status: count stash entries in separate function
  status: print stash info with --porcelain=v2 --show-stash
