|
|
" Return the command modifiers |<mods>| passed in raw as a:mods.
|
|
" In order to support older Vim versions that don't have this, one cannot use
|
|
" <q-mods>; this isn't understood and raises an error. Instead, we can benefit
|
|
" from the fact that the modifiers do not contain special characters, and do
|
|
" the quoting ourselves: '<mods>'. Now we only need to remove the identifer in
|
|
" case it hasn't been understood, and this is what this function is about.
