Merge branch 'js/am-call-theirs-theirs-in-fallback-3way' into maint

One part of "git am" had an oddball helper function that called
stuff from outside "his" as opposed to calling what we have "ours",
which was not gender-neutral and also inconsistent with the rest of
the system where outside stuff is usuall called "theirs" in
contrast to "ours".

  am: counteract gender bias
