Capitalize-last-word doesn't work with {^'s}

[arxanas]

Classification: Bug

Reproducibility: Always

Summary

Suppose you have this dictionary:

"TPAO": "foo",
"KPATS": "{*-|}",
"AES": "{^'s}

Then I expect the sequence

TPAO/AES/KPATS

to produce

Foo's

but it actually produces

foo'S

which is to say that it capitalizes the "s" in the suffix rather than the real beginning of the word.
