35168: Improve parsing of case patterns.

"|" is now found properly by looking for words that come
from the lexical analyser, rather than hacking a pattern
returned in one dollop.

Update some completion functions that need extra quoting
as a result.

Add test for new parsing.

Update version number to 5.0.8-dev-3 because of wordcode
incompatibility.
