Subject: popsbr.c: Alter traverse() to check action callback's result.
X-Git-Url: https://diplodocus.org/git/nmh/commitdiff_plain/bb0b14bdb72ac3b3fbee4ba4ff4da0b7848089bf?ds=sidebyside;hp=bb0b14bdb72ac3b3fbee4ba4ff4da0b7848089bf

popsbr.c: Alter traverse() to check action callback's result.

The action callback returned zero, with a 1999 comment asking if it was
checked.  traverse() didn't check it.  Change it so it does, wanting
`OK' if all's well, else returning the non-OK value to traverse's
caller;  though that only checks for NOTOK.  No functional change
intended.
