When using an external pager, commands other than return do not work from the `Press return to return to elm' prompt. The forked child carefully exits with the key pressed as its exit status, but the parent throws the information away. It's even commented ... we care! This patch is for Berkeley systems only I'm afraid. Other systems should use `return((status >> 8) & 0xff);' this would work on Berkeley too if status was always declared as `int', rather than as `union wait'. -- RCS file: /usr/local/src/elm/src/showmsg.c,v retrieving revision 2.1 retrieving revision 2.1.1.1 diff -c -r2.1 -r2.1.1.1 *** /tmp/,RCSt1a02728 Tue Dec 20 12:00:42 1988 --- /tmp/,RCSt2a02728 Tue Dec 20 12:00:44 1988 *************** *** 548,554 **** signal(SIGINT, istat); signal(SIGQUIT, qstat); ! /** used to return status, but who cares?
