Prior to this change the added test fails for me locally at byte 1024. It might depend on some default buffer sizes. Fixes <https://bugs.gnu.org/35863>. * tests/utils.scm ("canonical-newline-port-1024"): Add test. * guix/utils.scm (canonical-newline-port): Correct comments on CR/LF. Remove CR even when they're at the end of the buffer. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
