[PATCH/RFC] Allow file removal when "git commit --all" is used.

[Junio C Hamano <junkio@cox.net>]

After you deleted files from your working tree, automatic
git-update-cache used when the "--all" flag is given to "git
commit" barfs because it lacks the --remove flag.

It can be argued that this is a feature; people should be
careful and something with a grave consequence like removing
files should be done manually, in which case the current
behaviour may be OK.

The patch is for people who thinks the user who uses the "--all"
flag deserves the danger that comes with the convenience.

Comments?
