I see :-)
fwiw, it's been in screen a while. I see it in 3.7.1 (1995).
This comment in patchlevel.h appears to describe the change
* 27.04.94 -- 3.05.10 97801 obscure code support. Linux long
* password workaround.
But it wasn't in the terminal description using these capabilities:
parm_index indn SF scroll forward #1
lines (P)
parm_rindex rin SR scroll back #1 lines
(P)
...
Parameterized versions of the scrolling sequences are indn and rin
which have the same semantics as ind and ri except that they take one
parameter, and scroll that many lines. They are also undefined except
at the appropriate edge of the screen.
(The non-parameterized ind/ri could have used this, but already
had been assigned to sequences which a VT100 would recognize).
Actually I'd thought the tmux program would select "tmux" if available,
in preference to "screen', but a quick check of the source
code doesn't support that idea.
For example, in options-table.c:
{ .name = "default-terminal",
.type = OPTIONS_TABLE_STRING,
.scope = OPTIONS_TABLE_SERVER,
.default_str = "screen"
},
I'll check for anything I may have overlooked,
and probably add a somewhat longer note, explaining the situation.
