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.

will not do utmp and wtmp accounting for that process. This is needed for
gettys that insist on doing their own utmp/wtmp housekeeping. This is also
a historic bug. The length of this field is limited to 127 characters.
Please note that including certain characters in the process field will result
in
.B init
attempting to launch a shell to interpret the command contained in the process field.
The characters which will trigger a shell are:
.B ~`!$^&*()=|\{}[];\"'<>?
On systems which do not have a shell to be launched or which do not wish to
use a shell to interpret the process field, the process field can be prefixed
with the @ symbol. The @ will be ignored and everything followed will be treated
as a command to be launched, literally, by the
.B init
service.
In cases where both a + and @ sign are to be used (to turn off logging and shell
interpretation), place the + sign before the @ symbol. Both flags will be handled
and then everything following the @ will be handled by
