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. ^ permalink raw reply [flat|nested] 8+ messages in thread

Please don't. We do not want a "style conversion" for the sole purpose of conversion, especially when a subsystem is already internally consistent. Besides, the git-prompt.sh thing needs to be fairly bash specific so the usual "Git Porcelain scripts targetted for POSIX/Bourne shells" rules does not apply there. > My original gripe was just with doing it in one place while leaving all > the others unchanged. It makes for messy reading and leads to confusion. Yes, it is always preferred to match the _local_ convention. ^ permalink raw reply [flat|nested] 8+ messages in thread
