By the way, does this patch (and the other symlink-escape ones) need to
be marked with the SYMLINKS prereq? For a pure-index application, it
should work anywhere, but I have a feeling that this "git apply patch"
may try to write the symlink to the filesystem, fail, and report failure
for the wrong reason. I don't have a SYMLINK-challenged filesystem to
test on, though.
