Subject: pcase and minus-sign
Date: Wed, 30 Nov 2016 13:12:23 +0100 [thread overview]
Message-ID: <b81471ed-3cc9-9b50-4166-1f89e75d311a@easy-emacs.de> (raw)
Hi,
see code below. With numerical argument "1", first pattern is matched as
expected.
However without arg the minus is matched - the second pattern, not the
default "_" at last.
Any explanation?
Thanks,
Andreas
