# These bindings manually map the ANSI escape sequences for arrow
# keys.  Some terminal emulators, older systems, or misconfigured
# $TERM values can cause Bash to misinterpret or ignore arrow key
# input.  By explicitly binding these sequences, you ensure reliable
# cursor movement and history navigation in edge cases where default
# handling breaks down.  This can be particularly useful in SSH
# sessions, weird terminal setups, or when dealing with stripped-down
# systems where the termcap/terminfo database is incomplete or buggy.
