not a PATCH: fix/break indenting in _arguments docs

[Mikael Magnusson <mikachu@xxxxxxxxx>]

I probably have no idea what I'm doing, but without doing this the
whole rest of the text from the point of the enditem on goes back on the
same column as the tag names in the man pages. Ie, the end of the
_arguments text looks like this:

       The last two descriptions say what should be  completed  as  arguments.   The
       first  describes  the  first  argument as a `postscript file' and makes files
       ending in `ps' or `eps' be completed.  The last description gives  all  other
       arguments the description `page numbers' but does not offer completions.     

       _cache_invalid cache_identifier
              This function returns status zero if the completions cache correspond-
              ing to the given cache identifier  needs  rebuilding.   It  determines

The first place it seems to go wrong is here:

                     refer  only  to  the  words after the option.  When preceded by
                     three colons, they are modified to refer only to the words cov-
                     ered by this description.

       Any  literal  colon  in  an optname, message, or action must be preceded by a
       backslash, `\:'.                                                             

For some reason the subsequent text gets unindented after an enditem()
instead of staying at the same level. I initially suspected my yodl was
broken, but sshing in to some other hosts it looks like they have the
same problem.

With the patch however, the indenting is totally wrong in the pdf version,
and it was correct before there.

Other places seem to nest startitem()s without any problem. Maybe I
should look at some yodl docs one of these days.
