Log Message:
PR/28744: Ed Ravin: crontab with fewer than 3 comment lines dumps core
in crontab -l.
The problem is that the skip_header code has a side effect of trying to
write to the new temporary cron tab if we run out of comments. Since we
don't have an output file in -l, we core-dump trying to fputc to NULL.
Simplify the logic so that we don't write in the skip_header function,
and we always return the first character after the comment lines to the
caller, skipping the '\n'.
