For another approach, pretty much what you suggested, look at the
VarTab() function in foo.vim, my file of example vim functions:
http://www.vim.org/script.php?script_id=72
This function returns a calculated number of spaces, and it should be
pretty easy to use the same idea for your function. (It just takes a
little :while loop.)
I've had a play with this approach and it looks like it works (I'd still
be interested to know how to solve the problem mentioned in my other
email of course). In case it's of interest to anyone, the
implementation is included below.
