Mutt/1.2i |
This patch is the first step in making ESC key to work as it should (I
see that there is some code to make it work on Win*). It basically
"does nothing": macroizes checks for interrupt characters.
The purpose of this patch is to make it easier to identify places
which depend on how the interrupts are implemented. In several places
I (effectively) changed (c==7) to (c==3||c==7), but these places had 3
converted to 7 anyway beforehand...
Enjoy,
Ilya
