Update manual pages with markup and spacing fixes.

Added ability to use "@" symbol in command named in the inittab file. This
treats commands as literal and does not launch a shell to interpret them.

Updated inittab manual page to include overview of symbols which trigger
a shell interpretor and how to disable them using the @ symbol.
