Subject: write-tree: check extra arguments and die but be a bit more helpful.
X-Git-Tag: v0.99.9m^2~58

write-tree: check extra arguments and die but be a bit more helpful.

"git-write-tree junk" complains and dies, but it does not say
what option it supports.  Die with the usage string in such a
case.
