Minor quoting etc. fixes to misc manuals

Fix some minor quoting and spacing issues.  Distinguish more
clearly among grave accent and apostrophe (which are ASCII) and
single quote (which is not).  Prefer the standard terms
"apostrophe" and "grave accent" to alternative names that can be
confusing.  Use apostrophes to single-quote ASCII text.

* src/window.c (Frecenter): Use the same code for GUI and TTY
frames alike; use vmotion only for "initial" frames.  This is
because vmotion doesn't support visual-line-mode.  Rewrite the
'iarg >= 0' case to use move_it_* functions instead of using
vmotion, for the same reason.  Fix the clipping of the argument
value to support scroll-margin in all cases and avoid unwarranted
recentering.  Reported by Milan Stanojević <milanst@gmail.com> in
