[mythtv] CTRL or SHIFT keybindings to ESCAPE (r9163)

[Wolfgang Nothdurft]

Hi,

line 1077 in libs/libmyth/mythdialogs.cpp

if (e->state() != 0)
         return;

prevents that it is not possible to exit from plugins with Ctrl or Shift 
in ESCAPE keybindings. Is there any reason for this behavior.
I have a remote control that maps the exit key to Ctrl-Shift-H.
I think something like the following is more usefully or break this code 
other functions?

if (e->state() != 0) && !((e->state() & Qt::ShiftButton) || (e->state() 
& Qt::ControlButton))
         return;

thanx
Wolfgang
