Hi Ludo,

Sure, done! A new patch follows in my next mail.

But, I have always wondered, why do we not leave all the SRFIs as
external packages outside guile? That way, older versions of guile and
other scheme implementations might use them as well. It's a pity that I
have had to make many of guile packages strictly guile 3+ just because I
use SRFI-171.

I'd love to do that, but if I do, doc-markup fails to read the
gemtext.scm source file properly. The backtrace follows. doc-markup will
have to be fixed. May I push this patch and work on that separately
later?
