Revision 4e27fb06f0fe4206606172f94a18e08d7d87c070 authored by Nicolas Pitre on 06 October 2006, 19:39:09 UTC, committed by Junio C Hamano on 10 October 2006, 03:23:09 UTC 
add commit count options to git-shortlog
 
This patch does 3 things:

1) Output the number of commits along with the name for each author
   (nice to know for long lists spending more than a screen worth of
   commit lines).

2) Provide a switch (-n) to sort authors according to their number of
   commits instead of author alphabetic order.

3) Provide a switch (-s) to supress commit lines and only keep a
   summary of authors and the number of commits for each of them.

And for good measure a short usage is displayed with -h.
