The git add -A command can be used to conveniently add all files, whether they are tracked or not yet tracked (excluding the ones ignored via .gitignore/.git/info/excludes).

This convenience would come in quite nicely in the stash/commit commands, too (in the latter case, many test cases could be simplified using this new option).

The git stash command already has the --include-untracked option that does this, but not the short-and-sweet short option -A. The git commit command does not have any equivalent (it has the --untracked-files option, but that is really just modifying the output of git status).

Sadly, we cannot add --all, too, as that is already used for something different in git stash: it includes the ignored files, too. Likewise, git commit --all commits all tracked files, and does not add the untracked files (unlike git add --all).
