Research direction

No file or test is named. Start by tracing Mosh's backspace prediction path and its termios handling; compare the fixed 0x7f match with the configured erase character. Done means prediction works when erase is BS (^H), with the treatment of termios erase2 resolved.

Description

feature

Mosh's prediction for backspaces has a fixed match for 0x7f, or DEL. It should use whatever is set as erase in termios, for those people who use ^H/BS. Some termios support an erase2 character, which is typically used to allow both DEL and BS to be used; I'm not 100% sure we should handle that too.
