df2a700f9f Use `.Pq Ql'' to quote single characters, instead of `.Pq Li''. 
This makes the resulting output more aesthetically pleasing in
text-only terminals:

9ac1091d8c When listing the special $ variables, ($!, $#, etc) list them as $! 
instead of just !, this allows one to more easily locate/understand
the section of the manpage in question.

96265e088e Remove the printf builtin command from sh(1), which command is not 
used so often that it's worth keeping it as a builtin.

Now that all the printf invocations from within the system startup
scripts, we can safely remove it.

Urged by:	sheldonh  :)

No MFC is planned so far because it may break compatibility and
violate POLA.

b58a3e4078 Make test(1) a builtin command of our sh(1) for efficiency. The 
binary size increase is 3,784 bytes (about 0.6%).

I don't drop the printf builtin while I'm here because some /etc/rc.*
scripts seem to use it before mounting /usr where printf(1) resides.

4345758876 mdoc(7) police: 
Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
