Re: [PATCH v2] log: grep author/committer using mailmap

This is about your rewritten implementation that hasn't escaped to
the general public but sitting in 'next', right?

Two things that immediately come to mind are:

 - initialization of lowermail can use strbuf_init() instead;
 - downcasing can be done in place, i.e. "lowermail.buf[i] = ...".

Yep,
I don't think it's merged to 'next', I will squash those changes appropriately.
