You are right. I think I've got your point.
Here is the updated patch in which I added the multiple-character versions for backslash commands
and remove their corresponding single-character version.
Of course, for backslash commands with only single-character version, no change added.
BTW, I've done the existing tap-tests for tab-completion with this patch, all tests passed.
