If I don't do that there is no problem with an `a|b|c` regex. > I'm afraid I'm not > familiar with the --follow code so I've no idea how to fix this. I'm honestly unsure what the right behavior _should_ be, now. I expected --grep to be applied very late in the process, after the set of commits touching the specified file had already been computed (including all of its previous names, because of --follow) but the documentation is ambiguous. zw
