I narrowed this down to adding "exec" to the second pledge:

+_AT_@ -803,7 +809,7 @@ ttynew(const char *line, char *cmd, const char *out, char **args)
+ break;
+ default:
+ #ifdef __OpenBSD__
+- if (pledge("stdio rpath tty proc", NULL) == -1)
++ if (pledge("stdio rpath tty proc exec", NULL) == -1)
+ die("pledge\n");
+ #endif

with the added "exec", the program in openurlcmd gets executed. What I don't
know, however, is why is st not aborted if it is in violation of pledge,
instead of silently failing. The changed pledge is in the parent, which
continues execution.

Disregard this, it was due to having the debug version of script in openurlcmd
still installed in the system.

Anyway, I have attached the proposed "0.8.5" diff with this message. Is it ok
if I try to commit it to the wiki?
