* input-scrub.c (input_scrub_push): call input_file_begin, not
input_scrub_begin.
messages.c (as_perror): print ": " between the passed in error and
the strerror, like perror does.
* messages.c (as_warn): Use fputs, not fprintf, with a buffer that
has already been formatted (but may still contain %-characters).
(as_bad): Likewise.
