Sure, they are.  It's well possible I got something wrong when I
looked at Schwarzenberg's patch.  As I understood it, usually you have
a tag already and are interested in where to find the definition.
Looking up a *given* tag in the hash table construction is fast.

But if we are interested in the tags which match certain criteria, it
looks cumbersome.  All I meant in the quote is I generally prefer to
just retrieve all the tags into a macro string and then sort things
out in the macro matching the wished tags there instead of writing C
code for this searching (like Schwarzenberg's patch does).
