The shell version had to call $diff_cmd twice, once to find the modified modules cared by the user and then again, with that list of modules to do various operations for computing the summary of those modules. On the other hand, the C version does not need a second call to $diff_cmd since it reuses the module list from the first call to do the aforementioned tasks. In the C version, we use the combination of setting a child process' working directory to the submodule path and then calling 'prepare_submodule_repo_env()' which also sets the 'GIT_DIR' to '.git', so that we can be certain that those spawned processes will not access the superproject's ODB by mistake. A behavioural difference between the C and the shell version is that the shell version outputs two line feeds after the 'git log' output when run outside of the tests while the C version outputs one line feed in any case. The reason for this is that the shell version calls log with '--pretty=format:' whose output is followed by two echo calls; 'format' does not have "terminator" semantics like its 'tformat' counterpart. So, the log output is terminated by a newline only when invoked by the user and not when invoked from the scripts. This results in the one & two line feed differences in the shell version. On the other hand, the C version calls log with '--pretty=' which is equivalent to '--pretty:tformat:' which is then followed by a 'printf("\n")'. Due to its "terminator" semantics the log output is always terminated by newline and hence one line feed in any case. Also, when we try to pass an option-like argument after a non-option argument, for instance: git submodule summary HEAD --foo-bar (or) git submodule summary HEAD --cached That argument would be treated like a path to the submodule for which the user is requesting a summary. So, the option ends up having no effect. Though, passing '--quiet' is an exception to this: git submodule summary HEAD --quiet While 'summary' doesn't support '--quiet', we don't get an output for the above command as '--quiet' is treated as a path which means we get an output only if a submodule whose path is '--quiet' exists. The error message in case of computing a summary for non-existent submodules in the C version is different from that of the shell version. Since the new error message is not marked for translation, change the 'test_i18ngrep' in t7421.4 to 'grep'.
