Is using something like "__GIT_WORK_TREE_NOT_SET__" that terrible?

Yes.  First: it looks more like a C constant than a proper environment
variable.  Second: what to do _sanely_, when both GIT_WORK_TREE and
GIT_WORK_TREE_NOT_SET are true?

Sorry I was unclear. The discussion was about using a special value to
denote "this is not set." So I meant something like:

GIT_WORK_TREE="__GIT_WORK_TREE_NOT_SET"

There may not be precedent in git, but it is not unusual to use a
double-underbar prefix to denote private names and/or values. While in
theory a user could have a directory named as such, it would seem
highly unlikely. This looks a little cleaner to me than using ":", "
", or "/dev/null".
