Some of us are (of course we don't use Emacs for our jobs but for all
the other stuff it is good at).

Eli is right that Emacs using terms like tracking (etc) would be more

with a background in typography since the likelihood of it doing what
we expect is probably slim.

"char-spacing" lines up well with "line-spacing".
