Actually, why fight shell stuff when guile can read it?
Or are these modules not available in your context?
--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (use-modules (ice-9 textual-ports))
scheme@(guile-user)> (define ep (open-input-file "/proc/12430/environ"))
scheme@(guile-user)> (define es (get-string-all ep))
--8<---------------cut here---------------end--------------->8---
es from above got it all, when I tried manually as above.

FWIW I also did the same with (use-modules (rnrs bytevectors))
and the nulls show up as the expected zeroes.
