ignores .mailmap

git's log command allows for a mailmap file that "is used to coalesce together commits by the same person in the shortlog, where their name and/or email address was spelled differently". This is very handy for projects where a user has committed under different e-mail addresses.

It would appear that gitk does not support or use mailmap files.

From "man git-shortlog":

The .mailmap feature is used to coalesce together commits by the same
person in the shortlog, where their name and/or email address was
spelled differently.

If the file .mailmap exists at the toplevel of the repository, or at
the location pointed to by the mailmap.file configuration option, it is
used to map author and committer names and email addresses to canonical
real names and email addresses.

In the simple form, each line in the file consists of the canonical
real name of an author, whitespace, and an email address used in the
commit (enclosed by < and >) to map to the name. For example:

    Proper Name <email address hidden>

The more complex forms are:

    <email address hidden> <email address hidden>

which allows mailmap to replace only the email part of a commit, and:

    Proper Name <email address hidden> <email address hidden>

which allows mailmap to replace both the name and the email of a commit
matching the specified commit email address, and:

    Proper Name <email address hidden> Commit Name <email address hidden>

which allows mailmap to replace both the name and the email of a commit
matching both the specified commit name and email address.
