Hi Ludo,
Happy new year!

I've done the above by using the C functions to bind keyword arguments,
and added the #:use-path? keyword argument. One annoying thing though
is that since it uses keyword arguments, the first line of the
documentation generated by SCM_DEFINE only mentions "spawn program
. keyword_args".

I've opted to put it right below primitive-fork, and slightly rewrite
the part about pipes in primitive-fork's description to also mention
spawn. Let me know if the documentation is not descriptive enough.
WDYT?
