Title: Add an option to select the length of abbreviated sha1.

This was previously not configurable and done inconsistently in three different
places:

+ in 'log', the full sha1 was obtained and truncated to 8 digits
+ in 'branch', the sha1 was abbreviated, by git, to the default 7 digits
+ in 'status', the sha1 was abbreviated, by git, to the default 7 digits
