It looks like the less import broke this behavior (inhibiting ti/te
when invoked as more). See the changes between r1.7 and r1.8 of
contrib/less/screen.c.
$ cvs diff -u -r1.7 -r1.8 screen.c
...
- /*
- * This loses for terminals with termcap entries with ti/te strings
- * that switch to/from an alternate screen, and we're in quit_at_eof
- * (eg, more(1)).
- */
- if (!quit_at_eof && !less_is_more) {
- sc_init = ltgetstr("ti", &sp);
- sc_deinit = ltgetstr("te", &sp);
- }
-
+ sc_init = ltgetstr("ti", &sp);
if (sc_init == NULL)
sc_init = "";
+ sc_deinit= ltgetstr("te", &sp);
if (sc_deinit == NULL)
sc_deinit = "";
This seems to fix it:
