Title: Update bin/git-count

Matching "):" in the end can match commit subjects by mistake i.e. if
commit subject ends with "):" too (e.g. linux project has one such
commit).

To avoid this and any similar problems print summary only (-s).
Restructure output to look exactly as it was before with awk.
