Capital/upper case B doesn't register in either cygwin bash prompt, rxvt bash prompt, or ssh client bash prompt

bind -p lists all bindings, and every character that does not do a
special function should at least do self-insert.  If a key combination
is not bound, then it will not show up in bind -p.  Therefore, the
fact that bind -p | grep '"B"' failed to produce output is a good
indication that 'B' is not bound, and it can be rectified by:
bind B:self-insert
(where you use the key sequence [ctrl-v][shift-B] to actually
put B in the command line).

True, but I couldn't resist answering.
