* Don't ding the bell for completion or cursor movement out-of-bounds.
* Highlight completed filenames using the prevailing ls(1)
colours. (But continue not highlighting the existing prefix.)
* Do the bracketed-paste thing to make mis-aimed pastes less
dangerous. (This may also cause some annoyance, but I think I'm
willing to tolerate that for the extra safety.)
* Use Readline macros to bind M-SPC to a simulacrum of `just-one-
space'. The documentation of Readline macros is rather unclear
about which level the macro characters are inserted. It turns out
that they're keyboard macros.
