xkb: after making changes to the xkb ctrls, copy them back into kbdfeed.
enabled_ctrls_changes nowhere near the usual event or config paths. So this condition always evaluated to false and the memcpy would thus never been hit. As a result, any modification to the XKB struct during XkbUpdateDescActions was not reflected in the kbdfeed ctrls. The flag that is set by XkbUpdateDescActions() if ctrls were changed are in enabled_ctrls. This mainly affected keyboard repeat control as XKB uses the kbdfeed ctrls, not XKB's per_key_repeats, to determine if a key needs to be repeated. Thus, adding a "repeat= False" to the XKB map of any action did not have any effect. Test case: assign Mode_switch to any key that by default repeats, e.g. the menu key. key <COMP> { [ Mode_switch ] }; Then modify the Mode_switch action to not repeat the key. interpret Mode_switch+AnyOfOrNone(all) { virtualModifier= AltGr; useModMapMods=level1; action= SetGroup(group=+1); // Add this line repeat= False; }; Though the flags are correctly reflected in the description loaded in the server, the change is not handed back to the kbdfeed struct and XKB will trigger softrepeats of this key. This patch also adds two explanatory comments and an extra check, as this path may be hit before the CtrlProc for the kbdfeed struct is set. Red Hat Bug 537708 <https://bugzilla.redhat.com/show_bug.cgi?id=537708> Also fixes broken auto-repeat of the backspace key in the colemak layout (mapped to CapsLock).
