Binds with the same sequence in multiple modes was not working right.
Fix up the implementation to propagate modes everywhere as necessary.
This means that `bind` will properly list distinct binds with the same
sequence, and `bind -e` will take mode into account properly as well.
Note that `bind -e seq` now assumes the bind is in the default bind
mode, whereas before it would erase the first binding with that sequence
regardless of mode.
`bind -e -a` still erases all binds in all modes, though `bind -M mode
-e -a` still only erases all binds in the selected mode.
Rework for Doxygen >1.8. Moved large parts of the documentation to a
simplified format, making use of Markdown enhancements and fixing bad
long options.
plus speling in documentation for bind.
Note that this commit does not re-enable the generation of the manpage for
test, which will therefore still fall through to the system manual page with
`man test`.
