Subject: Allow backspace to be bound to keys in .nanorc
X-Git-Tag: v2.1.3~13
X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=fa406949ec5a49de68fba06c6c02f3fac9d2a335;p=nano.git

Allow backspace to be bound to keys in .nanorc
Allow kdel to be rebound
Add note about rebinding kdel to backspace for those using OSX or PuTTY to connect to remote Linux machines in nanorc.sample.in

When undoing text deletes, move current_x to proper location
