That it doesn't imply that the command takes refs in the form of ref1..ref2. > Isn't it just a misleading alias? No. It's an implementation detail that __git_complete_file() became an alias to __git_complete_revlist_file() to avoid unnecessary code duplication. And it was a concious decision to keep __git_complete_file() (and __git_complete_revlist()) around in order not to break completion scriplets for users' alieses and custom git commands which might call it. > > Arguably the name of __git_complete_file() could describe better what > > the function does, or what it did, i.e. it used to provide completion > > for the master:Doc<TAB> notation.

Indeed, and this "more" is exactly why it is misleading to call __git_complete_revlist_file() directly for git ls-tree and git archive. > > Now, __git_complete_revlist_file() provides completion both for this > > master:Doc<TAB> notation and for revision ranges, i.e. for > > master..n<TAB> and master...n<TAB>.

Which many many other commands do accept ref1..ref2:file?
