I know contrib/subtree does not work with anything other than bash,
and bash may accept this as a valid function name, but if you can
avoid it easily I would prefer not to see a non-POSIX construct like
this in my tree, even in contrib/ part:
http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_230
because people often reference random parts of the tree and mimick
what existing code does.

Is $prefix guaranteed not to have any $IFS whitespaces?

Doesn't "git subtree" honor TMPDIR? Not complaining, but being
curious.
