Correct, that was my reasoning behind it. Since shortlog is the only 
place in the documentation where mailmap is *directly* mentioned, it 
feels slightly tied to log. But, since blame and pretty.c also 
reference it, I needed the configuration option to be read as default.

Given that in total shortlog, blame, log, diff-tree, rev-list, show 
and whatchanged use it (the latter 5 through the pretty option), I'm 
tempted to say that it justifies its own option (mailmap.file?); but 
it would still have to be handled by git_default_config(). Renaming it 
would give it stronger reason to *be there* though.

I'm fine either way, really. Though, I think if we rename the option, 
it also justifies pulling the mailmap documentation out of 
git-shortlog.txt, into its own file, and link to it from shortlog, and 
the other commands which use it (git-blame.txt and pretty-format.txt)

I'll happily do the job, if "yay", or leave it as is if "nay".
Either way, feel free to rename log.mailmap to something else.
