[PATCH V2] bindings: make Refresh (^L) work at all the prompts again

[Benno Schulenberg]

  V2: The Refresh function is now also rebindable everywhere.

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

Bug existed since around version 2.1.0.

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