With an extern completion for git commit:

module completions {
  export extern "git commit" [
    -a
    -m: string
  ]
}

use completions *

I want to make a fixup commit that I will git rebase -i into the proper location on my branch.

nushell complains that "Batches of short flags can't take arguments."

❯ git commit -amf
Error: nu::parser::short_flag_arg_cant_take_arg (link)

  × Batches of short flags can't take arguments.
   ╭─[entry #441:1:1]
 1 │ git commit -amf
   ·              ┬
   ·              ╰── short flag batches can't take args
   ╰────

But ^git allows this:

❯ ^git commit -amf
[drbrain/some-branch abcdef01] f
 1 file changed, 1 insertion(+)

Describe the solution you'd like

When a short flag is in trailing position it accepts arguments as git does, or sort(1) does:

❯ echo "a 2\nb 1" | ^sort -hk2
b 1
a 2
❯ echo "a 2\nb 1" | ^sort -hk1
a 2
b 1

Describe alternatives you've considered

I can work around this by adding a space between m and my message ("f")
