|Thank you for trying to reproduce it.
Note i have no idea and did not truly look into the issue, but
there is a problem with terminals and the lowermost, rightmost
cell. Ie i have, which names termcap/terminfo capabilities
mx_TERMCAP_QUERY_am, /* am/am, BOOL | auto_right_margin */
mx_TERMCAP_QUERY_sam, /* sam/YE, BOOL | semi_auto_right_margin */
mx_TERMCAP_QUERY_xenl, /* xenl/xn, BOOL | eat_newline_glitch */
But i am (the mailer i maintain, at least, does) not doing this
completely right, as can be done.
However, most programs either do not use the lowermost/rightmost
column to avoid cursor wrap if written there, or otherwise deal
with those capabilities.
I have zero idea on what st does though.
Hope that helps.
