Can we just use that directly? The only reason I could imagine for not doing that would be to keep the same exit code, or the exact same message we had in the shell script. But we're doing neither here. The shell script used to die with exit code 1, while here we're exiting with 128, and the message is now prefixed with 'error: '. One other thing is that we're free'ing 'info' before printing revision. As revision is basically 'info->revision.buf', and we're freeing that we may end up printing garbage here. > + } > +} > + > +static int get_stash_info(struct stash_info *info, int argc, const char **argv) > +{ > + int ret;
