[RP] Using q as ratpoison escape character disables <ctrl+q> (<ctrl+q>+q)

[Thibault Hild]

I'm using ratpoison with a .ratpoisonrc file starting with:
escape C-q

When I hit <ctrl+s> in a terminal to stop the flow, I cannot use 
<ctrl+q> to start it again. This is the same as <ctrl+t> with the 
classic ratpoison escape character.
To allow the use of <ctrl+t> in a classic ratpoison configuration, one 
should use <ctrl+t>+t. So I tried to do the same for <ctrl+q> and I hit 
<ctrl+q>+q but the terminal flow is still blocked.

The behaviour is the same between ratpoison-1.3.0 and 1.4.0-beta4.
Has anyone else experienced this ?
Is there a workaround (changing the ratpoison escape character is not an 
option ;)) ?

Thibault.
