ANNOUNCE: GHC version 6.10.1 - EditLine / terminal incompatibility?

[Simon Peyton-Jones]

Would it be worth adding this hard-won lore somewhere on a Wiki where it can be found later?

| Thanks Judah.
|
| To save everyone else having to read the man page and working out
| through trial and error what the key escape codes are, add the following
| to your ~/.editrc file.
|
| # mappings for Ctrl-left-arrow and Ctrl-right-arrow for word moving
| bind "\e[1;5D" vi-prev-word
| bind "\e[1;5C" vi-next-word
|
| (though from reading the readline /etc/inputrc it suggests that "\e[5C"
| and "\e[5D" might be right on some systems)
|
| It's unfortunate that editline does not seem to support any
| global /etc/editrc file which would enable distros to make it do the
| right thing by default like they do for readline.
