More correct != correcter, More fun != funner

**The Error**
harperls tries correcting more correct => correcter, more fun => funner

**References**
English

**Potential Edge Cases**
Not sure if there's a good solution to this besides a lookup table for all the times where "more X" is better replaced by "Xer"

No file or test is named. Start by reproducing the reported “more correct” and “more fun” cases, then trace the comparative-correction behavior; done means those phrases are no longer changed to “correcter” and “funner” while valid corrections still work.
