Hi Emacs developers.

In misc.texi (and ack.texi), there are misused Texinfo markups.

>>> start here
ack.texi:1099:William Schelter wrote @file{telnet.el}, support for
@code{telnet}
misc.texi:1513:would from a regular terminal (e.g., using the @code{ssh} or
misc.texi:1514:@code{telnet} or @code{rlogin} commands), from a Term window.
<<<end here

I think these @code{...} markups should marked with @command{...}.

Thanks.
