Can't move cursor with arrow keys inside pry mode

[Charo-IT]

Seems like gdb's readline and Ruby's readline are conflicting.

Workaround
Use these shortcuts instead of arrow keys:

• Ctrl-f: move forward
• Ctrl-b: move backward
• Ctrl-p: previous history
• Ctrl-n: next history

Launching pry breaks gdb's tab completion. :(

Another workaround
Use rb-readline which is a Readline implemented in Pure-Ruby.
