This hasn't been committed.

I found it:

       -S list, -s list, --sections=list
              List is a colon- or comma-separated list of `order specific'
              manual sections to search.  This option overrides the $MANSECT
              environment variable.  (The -s spelling is for compatibility
              with System V.)

That's on linux; the 'else if' branch just above the diff context
implements that syntax.

896f43c broke that syntax too: the new %% causes a pattern syntax
error.  Your patch doesn't fix this problem (since it keeps the %%).

I'm therefore attaching an alternative patch which I believe will fix
both that issue and the issue you originally saw:

Testing on various OSes would be appreciated.

Thanks,

Daniel
