Hm, what happens if you use one of the following {rhs}es in a
Normal-mode mapping? Then you wouldn't need to copy the ex-command
register contents except when you really need it.
:exe @:<CR>
or
:let @@ = @: <Bar> exe @@<CR>
or
:let @@ = @: <Bar> normal @"<CR>
Notes:
1. I'm clobbering the unnamed register as the one least likely to hold
"valuable permanent data".
2. The above is for use in a mapping. To try it directly at the
command-line, use | instead of <Bar> and hit the Enter key (to execute
the ex-command) instead of <CR>.
Best regards,
Tony.
