I very much agree with your assessment, as my understanding is that
the command is primarily for debugging your .gitignore pattern by
eyeballing the output from it (as opposed to a serious tool to see
if a particular path is or is not ignored), so I am not surprised if
its exit code handling is buggy, and I am not suprirsed at all if
nobody has even noticed it is buggy ;-).
