`37.3 Creating a Synchronous Process' sez, repeatedly, that the
synchronous processes created are called "in a separate process."

Now, either that is obvious, since when you create a process it is of
course a separate process from Emacs, or it means something that I can't
guess at.  It's confusing because shell-command-to-string conspicuously
leaves out the words "in a separate process," leading me to wonder if
it's doing something fundamentally difference and to think maybe I can't
really replace invocations of shell-command-to-string with
(appropriately reformulated) invocations of call-process-shell-command,
as I plan to.

I'm not sure there is any special significance to the "separate process"
thing, it might just be a turn of phrase that was copied from some
original description as more of these call-process etc functions were
added.

If you look at how shell-command-to-string and
call-process-shell-command are actually implemented, both use
`call-process', just in different ways.

I've tweaked the places that use this phrase to make it clearer.
