Hi all, sorry for top posting :-( blame the phone and k9

I have a small issue with the use of test instead of [
If that only applies to this section of the entire file. 
Coding style has some value.

Combining nested ifs with && seems harmless enough, though should be
well tested.

Cheers

Ah, indeed, I looked around a bit more, and as per
http://mywiki.wooledge.org/BashPitfalls it seems like 'test' is bad to use with multiple &&'s anyways.

I think you are misreading a suggestion that is somewhat misguided
(yes "[ <condition> && <another> ]" does not make sense, but that is
not applicable to "test <conditon> && test <another>"); ignore it.

It is fine to write "test <condition> && test <another>" and that
works portably to even pre-posix systems.

But the existing code the patch touches favors [] over test
consistently; that alone is a good reason to stick with [] in _this_
script, even though it is against Git's overall shell script style.
