[PATCH] t/t7001-mv.sh: Propose ability to use git-mv on conflicting entries

[Petr Baudis <pasky@suse.cz>]

Currently, git-mv will declare "not under source control" on an attempt
to move a conflicted index entry. This patch adds an expect_failure
testcase for this case, since this is an artificial restriction. (However,
the scenario is not critical enough for the author to fix right now.)

I don't really know if it is ok to make "feature requests" like this by
adding failing testcases...
