Vim doesn't know where the text to be replaced starts, thus you need to
give only the part that it expects. You have to strip the first part,
which is identical in every returned item.

It's impossible to do this correctly in all situations. That's why it
is left to the completion function, because it's the place where the
desired behavior is known.
So yes, it's a bit more work to write the completion function if you
have arguments with spaces in it.
The 'completefunc' has a separate call to find the start of the
completed item. That makes some things easier, but also makes it more
complicated for simple completions.

I would like to get back to the Censor and agree to lose the shits, take
the odd Jesus Christ out and lose Oh fuck off, but to retain 'fart in
your general direction', 'castanets of your testicles' and 'oral sex'
and ask him for an 'A' rating on that basis.
