Since the '\' is the escape character, and since troff can sometimes
interpret text several times (eg. in diversions), use of '\' must be
sort of recursive (i.e.  one get's stripped off each time the text is
read), one either has to change the escape charater to something else,
or use the special character "escape", which prints the equivalent of
the current escape character ("\e").  It is in The Fine Manual!  :-)

One doesn't.... these are the "compacted" versions, with what little
comments and indendation from the sources removed.... at least not
without going slightly insane!

I usually re-indent them if I must try to read them.

There's also macref from DWB that will do cross-reference listings.
