Subject: patch 8.2.3462: ModeChanged only uses one character for new_mode and old_mode
X-Git-Tag: v8.2.3462
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d85931e67316e824878000d0ead122553ccef3a4;p=vim

patch 8.2.3462: ModeChanged only uses one character for new_mode and old_mode

Problem:    The ModeChanged event only uses one character for the new_mode and
            old_mode values.
Solution:   Pass one as first argument to mode(). (issue #8856)
