I wanted to get date information in RFC2822 format out of a tag using git-for-each-ref; but there was no way to specify that. This patch addresses that omission by adding a --dateformat option.
For example (I'm in BST, +0100 at present):
$ git-for-each-ref --dateformat=normal --format='%(taggerdate)' refs/tags/v1.5.2 Sun May 20 00:30:42 2007 -0700 $ git-for-each-ref --dateformat=relative --format='%(taggerdate)' refs/tags/v1.5.2 4 months ago $ git-for-each-ref --dateformat=short --format='%(taggerdate)' refs/tags/v1.5.2 2007-05-20 $ git-for-each-ref --dateformat=local --format='%(taggerdate)' refs/tags/v1.5.2 Sun May 20 08:30:42 2007 $ git-for-each-ref --dateformat=iso8601 --format='%(taggerdate)' refs/tags/v1.5.2 2007-05-20 00:30:42 -0700 $ git-for-each-ref --dateformat=rfc2822 --format='%(taggerdate)' refs/tags/v1.5.2 Sun, 20 May 2007 00:30:42 -0700
The default is to use 'normal', which leaves existing behaviour unchanged.
