# Usage: remap_keybindings old_function new_function
#
# Clear all readline keybindings associated with OLD_FUNCTION (a Readline
# function) rebinding them to NEW_FUNCTION (`self-insert' by default)
#
# This requires bash version 1.10 or newer, since previous versions did not
# implement the `bind' builtin.
