Re: [PATCH] mingw: hot-fix t5615

That test made the incorrect assumption that the path separator character
is always a colon. On Windows, it is a semicolon instead.

Documentation/git.txt says that GIT_ALTERNATE_OBJECT_DIRECTORIES is
separated with ";" on Windows fairly clearly, and we should have
caught that.  

For the upcoming release there is no need for any further tweak on
your fix I am responding to, but in the longer term we would want to
turn this to path_sep=";" (or ":") and define it in the global
t/test-lib.sh, as it is plausible that we may want to prepend or
append to $PATH in the tests and that also needs ";" on Windows, no?

Are there other variables that is a list of paths that we care in
our tests?  I notice GIT_CEILING_DIRECTORIES does not have the
corresponding ": separated (on windows ; separated) list" in its
description in Documentation/git.txt but the documentation may need
to be fixed there as well?

Thanks for a quick fix.  Will apply on jk/alt-odb-cleanup and merge
down.
