I tried to figure out what the optional arg REMOVE is doing in
alist-get.  While I find the code of add-to-alist not too difficult to
grasp at a glance, the optional arg REMOVE is ignored in alist-get.  But
it is a more complicated call of gv-define-expander in gv.el that seems
to define REMOVE.  For less advanced users, this may be an extra barrier
to put such code into their init file.
