Right. I've pushed a patch that doesn't make suggestions for single-character names.

| If the match threshold at which candidates are reported is something
| like (length of identifier) `div` 4 then the match threshold for
| length-1 identifiers will be 0, so quite naturally no candidates will
| be reported.
