Subject: updated for version 7.3.980
X-Git-Tag: v7.3.980
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=745fc029ba7541ac08b93bb2304a1a407e73336b;p=vim

updated for version 7.3.980
Problem:    Regexp logs may contain garbage. Character classes don't work
            correctly for multi-byte characters.
Solution:   Check for end of post list.  Only use "is" functions for
            characters up to 255. (Ken Takata)
