Allow mapping feedkeys :exec … to take count into account

Is there an existing issue for this?

Problem

Currently I have a mapping of the following form

map <C-v> feedkeys ":exec xterm -e /home/user202729/useful-sh/zathura-open-in-vim         $PAGE $FILE<Return>"

Ideally I want to write

map <C-v> feedkeys ":exec xterm -e /home/user202729/useful-sh/zathura-open-in-vim         $PAGE $FILE $COUNT<Return>"

so that e.g. 5<C-v> would type :exec xterm ... $PAGE $FILE 5<Return>. It would also be good to have a special place holder for empty.

Expected behavior

For reference: the vim behavior is to map 3: to :.,.+2 (which in vim's context only makes sense as "from current line to 2 lines next"). Alternatively we can implement something similar to vim's v:count.

A potential disadvantage is then existing code that uses $COUNT will break — but I think this is negligible.
