Support yadm

[openjck]

I would like to support yadm if it wouldn't be too difficult. yadm is a dotfile manager which is essentially just a wrapper around Git. It has an almost identical CLI, with commands like yadm add, yadm commit, etc. I use it to manage my dotfiles.

If I could somehow determine the caller in the Bash scripts (either git or yadm), I could write the scripts to use the specific caller dynamically. That is, instead of using git ls-files internally, I could use $CALLER ls-files internally. That said, I can't currently think of a way to determine the caller dynamically.

I pushed some progress on this work to the yadm branch. I'm not sure I'm happy with how much more complicated this makes the project, though. It might be better to suggest that users do something like this, despite its drawbacks:

$ yadm enter
$ git iadd

One drawback is that this string of commands will pass way to fzf because the --others option is passed to git ls-files internally and yadm does not care about most files, although I could support a --no-others flag in iadd and other commands for yadm to use. Another drawback is that I don't think the process of first typing yadm enter can be conveniently automated. I'd like if users could, say, create a yadm-only alias of iadd which programatically runs yadm enter first, but I don't think it's possible to create yadm-only command aliases. I also don't think it's possible to override an existing, external command like iadd with an alias, even in normal Git.
