It would be nice for `make coverage` (or something) to produce a HTML
test-coverage report. I found this very useful for test-driven development of
[[plugins/contrib/trail]].
Limitations of the current branch, which uses [[!cpan Devel::Cover]]:
* Some tests use `./blib` and some use `.` so coverage gets split between
the two copies of each module; not a problem for [[plugins/contrib/trail]]
which only has one test.
> How annoying. I think in at least some cases there is reason to use
> `./blib` -- perhaps everything that users `.` should be changed to use
> it. --[[Joey]]
* The [[plugins/git]] and [[plugins/mercurial]] plugins want to `chdir`,
and so does [[!cpan Devel::Cover]], so they fight. For now, those tests
are disabled under `make coverage`.
