cmdline: for new tools avoid introduce new negative switches, and properly align --help texts
Negative switches are a bad un-normalized thing. We alerady have some,
but we should try harder to avoid intrdoucing new ones.
Hence, instead of adding two switches:
--foobar
--no-foobar
Let's instead use the syntax
--foobar
--foobar=yes
--foobar=no
Where the first two are equivalent. The boolean argument is parsed
following the usual rules.
Change all new negative switches this way.
This patch also properly aligns the --help table, so that single char
switches always get a column separate of the long switches.
