[PATCH] Make git blame date output format configurable, a la git log
From: <hidden>
Date: 2016-06-15 22:46:15
From: Eugene Letuchy <redacted>
Adds the following:
- git config value blame.date that expects one of the git log date
formats ({relative,local,default,iso,rfc,short})
- git blame command line option --date-format expects one of the git
log date formats ({relative,local,default,iso,rfc,short})
- documentation in blame-options.txt
- git blame uses the appropriate date.c functions and enums to
make sense of the date format and provide appropriate data
The tests pass. The mailmap test needed to be modified to expect iso
formatted blames rather than the new "default".
