Subject: Multiple paths in GIT_EXEC_PATH

Hello. After updating to a recent git release (2.14, I believe, but
possibly earlier), setting GIT_EXEC_PATH to multiple directories
stopped working. It did work before, and I believe the culprit is
'git-sh-setup', which uses 'git --exec-path' output directly, while
most other git components observe PATH syntax, i.e. multiple paths
with colon separator. Is this intended, or is it an oversight?

For why I need that is another matter. Long story short, I need git to
look for '.gitignore' in a particular non-standard location, since I
have multiple git repositories in the same workdir (that workdir being
$HOME and git repositories being stores for my different configs)
