Why not, it's just a couple of lines, but...

... I think at least the message should be improved to tell exactly what
is wrong with the request.
Other points worth noting:
- Maybe it's not only the query string (don't remember now, haven't
checked), long paths may get passed to cvs(1) too, right?
- The request URI length can be limited on web server level as well, for
example for Apache (1.3.2+) see the LimitRequestLine directive.
