Subject: git-gui: Refactor file state representations.
X-Git-Tag: gitgui-0.6.0~198
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=b67651129897738496a9dcd3c01129a42acd11db;p=git.git

git-gui: Refactor file state representations.

It just felt wrong to me that I was using _ as part of the mode argument
to display_file to mean "don't care/use existing" and * as part of
the mode argument to mean "force to _".

So instead use ? to mean "don't care/use existing" and _ to mean
"force to _".  The code is a lot clearer this way and hopefully it
won't drive another developer insane, as it did me.
