That's what it is in CVS HEAD.  But the C_is* stuff is quite new so it
may not have been like that in the last release.

That's the place.

It's Bison source (usually it's .y, but this is C++ so we use .yy) -
queryparser.cc is generated from queryparser.yy using Bison.

If you just want to make a minor tweak locally, modifying the generated
file is a reasonable approach.  If you do modify the .yy be sure to
configure with --enable-maintainer-mode or the file won't be regenerated!

That's the place.
