why does make check run all tests?

[phillip.lord@russet.org.uk (Phillip Lord)]

I've been looking through the Makefile for the test directory.

Currently, the check target says this.


## Re-run all the tests every time.
check:
	-@for f in *.log; do test ! -f $$f || mv $$f $$f~; done
	@${MAKE} check-maybe

I realised last night, that my recent changes have actually broken this
(check is now incremental).

This to me seems to be a good thing (although it was accidental). Why
should check run all tests everytime? Especially now that I have added
dependencies between tests and source (so, if you change abbrevs.el,
then abbrevs-test.el will get run).

Should make check just not build incrementally? If you want to run
everything unconditionally, then why not use

make clean check


Or am I missing something obvious? In which case, I will need to restore
the old behaviour for make check and leave make check-maybe as is.
