set-cursor enables abbreviations to specify the cursor location after
expansion, by passing in a string which is expected to be found in the
expansion. For example you may create an abbreviation like `L!`:
abbr L! --position anywhere --set-cursor ! "! | less"
and the cursor will be positioned where the "!" is after expansion, with
the "| less" appearing to its right.
