function! ingo#compat#command#Mods( mods )
"******************************************************************************
"* PURPOSE:
"   Return the command modifiers |<mods>| passed in raw as a:mods.
"   In order to support older Vim versions that don't have this (prior to
"   Vim 7.4.1898), 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.
"	-command! Sedit call SpecialEdit(<q-mods>)
"	+command! Sedit call SpecialEdit(ingo#compat#command#Mods('<mods>'))
"* ASSUMPTIONS / PRECONDITIONS:
"   None.
"* EFFECTS / POSTCONDITIONS:
"   None.
"* INPUTS:
"   '<mods>'
"* RETURN VALUES:
"   Usable modifiers.
