This continues the work started with the fix for #4273. There was another bug caused by using the subcommand names without considering their position in the argument list. If the user enters `git diff log <TAB>`, we build up a string that identifies the subcommand. We ended up making the string `git__diff__log` in this case because we appended `__log` without considering the current state. Since `git__diff__log` does not correspond to an actual command, we wouldn't provide any suggestions. This commit restructures the code so we walk subcommands and subsubcommands in `bash.rs`. While walking those, we build up a list containing triples of the parent `$cmd` name (e.g. `git__diff`), the current command's name (e.g. `log`), and the `$cmd` for the current command. We then build the shell script's case arms based on that information. We could instead have fixed #4280 by using the second element in the pair returned from `utils::all_subcommands()` (a stringified list of the subcommand path) instead of the first one. However, that would not have helped us solve #4265. Closes #4280
