Having done this same thing 5000 times my solution was to never type
long : command at the command line. Instead i type them into the file
where you get all your favorite editing features. i then delete the
line into a named buffer and then execture the buffer with the @
command. To speed things up i have a macro for control X in my .exrc
file the does the delete and execute for me. If the command didn't
behave as expected then i undo the change put the buffer, edit and
reexecute it. It works adequately for me.

Here is my macro. It uses the named buffer 'd'

map ^X "ddd@d

As an aside you can exploit the function key maping to extend your
macro set. VI lets you type #<digit> to simulate pressing a function
key. The versions of vi i use don't check to make sure that the
characters following the # are digits. i have many macros defined as
#<letter> so that at last count i had 43 macros defined.
