My understanding is that we only test in `foo-tests.el' functions
beloging to `foo.el'.
For historical reasons:
`zap-to-char' is defined in simple.el
`zap-up-to-char' is defined in misc.el

We can move the latter to simple.el, then test the functions in the same file.
Some people dislike that because it affects the Git history.
I am OK with whatever the people prefer here.
