Yeah, I think that compinit is overkill for simple file extension
completion.

Actually, {} globbing is valid ksh93 syntax.  It's not valid ksh88
syntax.  But I've always pictured zsh's ksh emulation as ksh93
emulation.

This got the wheel's turning.  Turn's out that 'emulate ksh' turns on
'SH_GLOB', which in turns disables (|) globbing.  Boo, not the expected
behavior since ksh expects these characters to enumerate shell globbing.

Turning off SH_GLOB makes everything work correctly.  Thanks for giving
me a path to track down.
