For long lines from a process, watch would wrap them around to the
next. While this default option has it uses, sometimes you want to
just cut those long lines down.
watch has a -w flag which will truncate the lines to the number
of columns. A few simple lines to do this new trick.
I think I caught all the ANSI state correctly but there might be
a chance it bleeds to the next row.

vmstat - align wording with proc manpage to clarify ambiguities (rhbz#1796043)
watch - manpage presumes ntp tools are present by default (which they're not on rpm and deb distros, rhbz#1583669)
--------------- Original Master Branch Commit Message:
The manual page for watch for the exec option was confusing and
backwards. Hopefully this one makes more sense.

Added locale details and fixed this manual page to follow standards
including ordering it the right way, keeping the names of things
consistent and removing authors section.

All warnings where about unnecessary quoting. The scriptlet
below will tell what was wrong.
for I in ./top/top.1 ./ps/ps.1 ./*.[0-9]; do
echo "== $I warnings =="
man --warnings=all $I > /dev/null
done
This should probably be turned to 'make check' script.

The -d, --differences switch(s) can use optional argument that was
not documented earlier.

Add new flags to watch (-g/--chgexit) so that it exits when the
output changes. This is useful in builds and shell scripts, for
example when deploying webapps to block the remainder of the
deployment steps until after the webapp starts.
e.g. watch --chgexit curl http://foo/bar
