For abbreviations |v:char| is set to the character that was typed to trigger
the abbreviation. You can use this to decide how to expand the {lhs}. You
! can't change v:char and you should not insert it.
Be very careful about side effects! The expression is evaluated while
obtaining characters, you may very well make the command dysfunctional.
