I think the intention of AS_HELP_STRING is that it formats both of its
arguments for you, i.e., adds newlines as appropriate when lines get too
long.  If that doesn't fit for me, I tend to just not use AS_HELP_STRING
but pass a literal, expanded string to AC_ARG_ENABLE (or whatever other
outer macro call you're using there), with indentation and newlines
where I need them.

I also think mixing automatic line wrapping with manual line wrapping
within one macro would not be a good idea.

Hope that helps.

Cheers,
Ralf
