ImGui: a suppressed text event no longer eats the next character (B8)

Browse Source 
Ctrl+V, the zoom chords and new-window set a one-shot flag to drop the
text event their key press would produce, but SDL sends none for Ctrl
chords, so the flag dropped the next character typed instead (typing
"xyz" after Ctrl+V gave "yz", reproduced under Xvfb). The flag now
applies only until the next key press. C-k and Meta suffixes are still
suppressed (checked: C-k s saves without inserting "s"; M-f moves
without inserting "f").
