CMUCL commit: src/code (unidata.lisp)

Modified: unidata.lisp

Was mishandling the case where there are no more completions.  In this
case we were returning the prefix string, but that would be incorrect
if the prefix string is not a valid character.  So check that it is
valid and return it.  Otherwise do nothing (thereby returning nil) so
slime can note the character is invalid.
