I'm writing generic text editing functions.  They don't care if it's a
full screen editor, line editor, or stream editor driving them, they do
text editing.  Ed, ex, vi, and sed all have "select lines with a regex,
do some editing function on them".  Lots of other things they have in
common to.  Including the ability to run "scripts" of their own
commands over text.

I read through the relevant standards and compiled lists of what they
do that is common, and what they do that is not so common.  Did the
same with the documentation for joe, microemacs, nano, and midnight
commanders editor.  Also included more, less, and readline.

Not gonna be all things for all people, but there's enough common stuff
for generalization to work out for us.

The toybox sed (as of 0.3.0) is a stub with "hello world" in it.  None
of the others have been written yet.  I think my stuff could be useful
to them all, and toysh as well (readline type stuff).
