Sorry for slow reply!

I would say that, yes, both check and check-maybe should skip expensive
tests by default. I think this actually contradicts the GNU coding
standards, but possibly it's these that need updating for very slow
tests.

I'd also agree about <foo>, <foo>.log (on master <foo>.log is
lisp/<foo.log>, and lisp/<foo> also exists).


However, I also think that these should also respond to setting
SELECTOR on the command line.

The problem with this patch:


+SELECTOR_DEFAULT = (quote (not (tag :expensive-test)))
+SELECTOR_EXPENSIVE = nil
+SELECTOR =

+check-maybe:
+	@${MAKE} check-doit SELECTOR="${SELECTOR_DEFAULT}"
+


is that "make check-maybe SELECTOR=nil" doesn't actually run the
expensive tests as it should. That was the reason for my original,
rather more complicated, suggestion.

I've attached a complete patch below (actually tested this time!), which
I think works. Would this make sense to you?
