Cursor offset with show-mode-in-prompt string

[inukshuk]

Description

I have the following config in my .inputrc to modify the cursor shape via escape sequences in the vi-mode-string variables:

set editing-mode vi
set show-mode-in-prompt on
set vi-ins-mode-string \1\e[6 q\2
set vi-cmd-mode-string \1\e[2 q\2

With these escape sequences in place the IRB prompt is offset (it reads rb(main) instead of irb(main)) and cursor/caret is placed at the beginning of the line (over the 'r') instead of at the prompt. Typing inserts the correct characters at the prompt and the cursor moves but keeps the original offset.

For example, typing the command p 1 would move the cursor as indicated:

rb(main):001> 
^
rb(main):001> p
 ^
rb(main):001> p 
  ^
rb(main):001> p 1
   ^
rb(main):002>
^

Looks like a config loading bug. q\2 part is ignored, maybe because it uses .split(' ').

Using \x20 might be a workaround

set vi-ins-mode-string \1\e[6\x20q\2
set vi-cmd-mode-string \1\e[2\x20q\2

@tompng good catch, thank you! Using \x20 to work around for now.
