xterm not supporting REP escape sequence
The xterm definition changed from ncurses-6.0 to ncurses-6.1:
comparing xterm to xterm. comparing booleans. comparing numbers. comparing strings. kmous: '\E[M', '\E[<'. rep: NULL, '%p1%c\E[%p2%{1}%-%db'. rmcup: '\E[?1049l', '\E[?1049l\E[23;0;0t'. smcup: '\E[?1049h', '\E[?1049h\E[22;0;0t'. u8: '\E[?1;2c', '\E[?%[;0123456789]c'.
Running an ncurses-6.1 application under teraterm causes horizontal window lines to be shortened to a length of one. The new REP sequence (repeat character) in ncurses-6.1 is probably the cause. ncurses-6.0 renders correctly in teraterm.
For reference, Putty added REP support in 0.71 (https://www.chiark.greenend.org.uk/~sgtatham/putty/changes.html), and I do recall seeing corrupted output when using older Putty.
Teraterm version is 4.103.
