Subject: updated for version 7.3.1261
X-Git-Tag: v7.3.1261
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=72179e1bd0bbb1d1c3083c85bd9fb0a8d6928f7f;p=vim

updated for version 7.3.1261
Problem:    A buffer-local language mapping from a keymap stops a global
            insert mode mapping from working. (Ron Aaron)
Solution:   Do not wait for more characters to be typed only when the mapping
            was defined with <nowait>.

+When defining a buffer-local mapping for "," there may be a global mapping
