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.
We are in total agreement then ;-)
I also agree that it would be a good idea to introduce a shared
documentlet similar to pretty-format.txt that can be included in the
documentation pages of commands that use this name-rewriting mechanism.
