The rest of the arguments would then be considered as the command. I don't think I change any visible behavior though (or at least trying not to). There are two command line parsers, the "front" one is in git-submodule.sh and should do what you describe (or whatever the current behavior is) and there's an internal one for "git submodule--helper" which is more like internal API than anything. The change here is to stop the internal parser from accidentally interpret options that belong to the foreach's command. The "--" and first non-recognized argument should be handled correctly by the front parser. The exact behavior of this front parser, I can't tell (I'm nowhere near expert level of submodules) but yeah it should stop at either `--` or the first non-option argument (e.g. something that does not start with '-'). An argument that looks like an option (i.e. starts with '-') but not recognized should result in an error. This is pretty much standard behavior for all other commands, but I have not tested this with git-submodule.sh. > This would slightly break the retrocompatibility, but would also avoid similar bugs in the future. -- Duy
