Trying to process patches that seem to be from the git equivalent of
"darcs send", I find that darcs doesn't accept the format for the date
headers they contain which I was hoping to use directly, e.g.
Date: Fri, 1 Jun 2012 14:04:53 +0100
GNU date accepts and emits them as RFC2822.
The following patch sent by Dave Love <email@example.com> updated issue issue2235 with
* Resolve issue2235: Accept RFC2822 dates
