1899e313fd as a fix for #3631 broke :unbind, as
the config system treats None and '' equally.
Instead, allow None/'' again, but just handle it as "no binding".
This mostly reverts 4ef5db1bc4 for #1966, but
fixes#3684 by allowing numbers to be bound again. If the user wants to bind
numbers instead of using them for a count, why not let them.
This handles Qt.KeypadModifier (Num+...) correctly, adds tests for converting
modifiers to strings, and strips Qt.GroupSwitchModifier as QKeySequence doesn't
know about it.
Fixes#3675
When pressing a key which doesn't exist as Qt.Key, we don't get Qt.Key_unknown
like we'd expect, but we get 0x0 instead...
Let's add that as a new "nil" key (to not conflict with None/unknown/zero/...)
and handle it appropriately.
This can be reproduced by doing:
setxkbmap -layout us,gr -option grp:alt_shift_toggle
and pressing Alt-Shift/Shift-Alt.
Turns out when we press yY, we get three events:
Qt.Key_Y, Qt.NoModifier
Qt.Key_Shift, Qt.ShiftModifier
Qt.Key_Y, Qt.ShiftModifier
If we don't ignore the second one, our keychain will be interrupted by the Shift
keypress.
Now that we don't rely on str(KeyInfo) being empty anywhere, there's no reason
to return an empty string for only-modifier keypresses anymore.
While those keys can't be bound (QKeySequence('Shift') == Qt.Key_unknown)
there's also no reason to explicitly ignore them.
