[PATCH] bindings: make Refresh (^L) work at all the prompts too

[Benno Schulenberg]

Unfortunately, this means that ^L cannot be used for the Linter in
the "Execute Command" menu.

Unfortunately, it also means that Refresh cannot be rebound at the
prompts -- because I do not want to list ^L in each and every help
text.  At the prompts, only ^L will work, and if ^L is bound to
something else, Refresh will be unavailable.  It's not a big deal,
because no one ever complained that ^L didn't work at the prompts
any more, so there is no real demand for it.  But it is nice that
it works at least in the default setup.

This fixes https://savannah.gnu.org/bugs/?58469.

Bug existed since around version 2.1.0.
