top: tweak the heck out of some command line help text

This patch began as just an attempt to make any option
which also included an argument a little more readable
by adding one space before the '=ARGUMENT' convention.

[ by the way, i don't agree with most of those other ]
[ procps-ng programs that use an '<arg>' convention. ]
[ it's too easily misread as an 'optional' argument. ]

[ top uses a convention like that found in coreutils ]
[ albeit now with one extra space before the equals. ]

In adjusting those arguments it was apparent that many
explanations already lined up nicely at the right hand
margin. So, this commit will force right-justification
with all explanations (as we do with commit messages).

[ and as a final challenge, for those options taking ]
[ an argument, that argument was repeated within the ]
[ explanation and made the rightmost item on a line. ]
