wishlist += command completion for deleted but tracked files

Hi,

in my work i had the following situation:

deleted a file that was already version controlled, git status is:

On branch master
Changes not staged for commit:
   (use "git add/rm <file>..." to update what will be committed)
   (use "git restore <file>..." to discard changes in working directory)
         deleted:    IQFE.cc
         modified:   ctirgl.cc
         modified:   joaogl.m

Would very much like to type:

"git checkout IQ" (and TAB) to complete to the already known filename "IQFE.cc"

This would be especially helpful for longer file names.

Thank you,

kind regards,

Andreas
