Make an explicit register on repeat override g:repeat_reg

Browse Source 
As with built-in commands, this allows to override the original register on repeat, e.g. "a. uses register a instead of the original one.

One limitation is that we cannot detect whether no or the default register has been given, so an override from a non-default to the default register (e.g. via "".) is not possible.
