In the present version of genparse new strings are always printed
in new lines. For example (also from the ls commmand):

d / directory                   flag    "list directory entries instead of 
contents,"
                                        "  and do not dereference symbolic 
links"

in the genparse (.gp) file is translated into

  -d, --directory            list directory entries instead of contents,\n\
                               and do not dereference symbolic links\n\

in the generated usage() function. Or

NONE / group-directories-first  flag    "" "group directories before files"

could be used to generate

      --group-directories-first\n\
                             group directories before files\n\

in the usage() function.

So presently it doesn't work, but your idea is not bad. I will think 
about it again and maybe change genparse such that multiple comment
strings in the same line will simply be concatenated.
