Subject: [PATCH] input: properly handle <Escape>s followed by a shifted
Meta+letter
After a series of escapes, also <Shift+Meta+letter> should be recognized
as a command keystroke, not just <Meta+letter>.
This fixes https://savannah.gnu.org/bugs/?55442.
Bug existed since the ignoring of <Escape>s before a valid command
keystroke was introduced in version 3.0, commit ecc9211a.
