setup_work_tree: adjust relative $GIT_WORK_TREE after moving cwd When setup_work_tree() is called, it moves cwd to $GIT_WORK_TREE and makes internal copy of $GIT_WORK_TREE absolute. The environt variable, if set by user, remains unchanged. If the variable is relative, it is no longer correct because its base dir has changed. Instead of making $GIT_WORK_TREE absolute too, we just say "." and let subsequent git processes handle it.

test-subprocess: fix segfault without arguments Check if we even have a parameter before checking its value. Running this command without any arguments may not make a lot of sense, but reacting with a segmentation fault is unduly harsh. While we're at it, avoid casting argv by declaring it const right away.
