fix bind command example given by fkr

Browse Source 
The `fish_key_reader` program emits an example `bind` command for the sequence
of keystrokes it sees. However, if that sequence includes a space or del
character the example `bind` command includes extraneous commentary that makes
the command invalid.

Fixes #3262
