[PATCH v2 11/17] am: counteract gender bias

[Johannes Schindelin <johannes.schindelin@gmx.de>]

Since d1c5f2a (Add git-am, applymbox replacement., 2005-10-07), i.e. for
almost 11 years already, we demonstrated our disrespect to the pioneers
of software development like Ada Lovelace, Grace Hopper and Margaret
Hamilton, by pretending that each and every software developer is male
("his_tree"). It appears almost as if we weren't fully aware that the
first professional software developers were all female.

We know our field to have this unfortunate gender bias that has nothing
to do with qualification or biological reasons, and we are very sad
about the current gender imbalance of the Git developer community.

Let's start changing that by using the variable name "her_tree" for an
equal number of years out of fairness, and change to the gender neutral
"their_tree" after that.
