We should only be able to get out of step from the "%_" case, I believe, so we should only need to do the first-byte test in that case (which is in a different code path from the normal "_" case. Does that seem right?

At least put Assert(IsFirstByte()) in the main path.

I'm a bit suspicious of the separate-path business anyway.  Will it do
the right thing with say "%%%_" ?



           /* %% is the same as % according to the SQL standard */
           /* Advance past all %'s */
           while ((plen > 0) && (*p == '%'))
               NextByte(p, plen);
