That's odd:

burner% echo $ZSH_VERSION
5.2-dev-1

I never get the "-dev-1" part in PATCHLEVEL.

Apparently here is a case that depends on wb / we always being updated,
or at least being initialized in some way that has been missed.

I won't have a chance to look at this for at least another 3 weeks, so if
anyone else cares to try deciphering the interaction of the lexer with
compcore, it's all yours.
