Subject: main: don't allow ESC key repeat to flood console
X-Git-Tag: 0.9.3~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1f1d83bf71fc4d1748bed3366fd6a597d34fbabd;p=thirdparty%2Fplymouth.git

main: don't allow ESC key repeat to flood console

If the user holds down ESC the system can easily get
overrun toggling details and the theme back and forth.

This commit changes the code to ignore any ESC key events
that come in while ESC is getting processed.
