A reasonable compromise would be using for searching the same syntax
table of the buffer that is current when the tags-search command is
issued.  This would not work in various situations, but would work in
most cases, and probably would work in many more cases than the current
situation.

If nothing smarter comes up and no one does it first, I'll try to
implement that in the next days.
