To all of you that helps out with the important tak of improving the Pike documentation (three, or so, people): The code/tt markup is now as follows.
General computer-stuff should be marked with @tt, e.g. @tt{--help@}, @tt{/bin/sh@}, @tt{POST@}.
Code expressions in flowing text should be marked with @expr, e.g. @expr{7@}, @expr{"POST"@}, @expr{i=i++;@}. Code expressions may be broken into several lines, as can @tt, but we have the possibility to break the expressions between tokens instead of at white spaces.
Code snippets should be marked with @code, e.g. @code int i=4; i=i++; @endcode
