A regression, then?  Sorry about that.

Could you clarify the precise LBUFFER/RBUFFER values that "won't
complete"?

What I had in mind in that commit was to complete the correct non-option
arguments after the options listed in the log message; e.g., «zstyle -s
<TAB>», «zstyle -s foo <TAB>», «zstyle -s foo bar <TAB>».

The «(-)» exclusions in the line changed were designed to make that line
complete the "set a zstyle" syntax, «zstyle foo bar baz» without any of
the options (not even -e, which is handled separately).

As written, I think the patch will cause «zstyle -g foo bar baz <TAB>»
to offer completions, whereas currently it correctly completes nothing.
(Just observing; not implying any conclusions.)

Cheers,

Daniel
(ENOTIME to test, sorry)
