I am trying to check if a lhs is already abbreviated in vim. mapcheck, however, seems to have a problem. For example,

iabbr swt switch
echo mapcheck('sw','i',1)

returns "switch" even when "switch" defined for "swt". mapargs seem to return a string even if there is a partial match with the lhs. Is there a way to find if an abbreviation has been defined for the "exact" match, i.e., the above mapcheck returning a "" instead.
