X-Git-Tag: v8.1.1459
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3f6aeba18b3e29da98ab9326e66d287a997d98d1;p=thirdparty%2Fvim.git

patch 8.1.1459: popup window border looks bad when 'ambiwidth' is "double"

Problem:    Popup window border looks bad when 'ambiwidth' is "double".
            (Yasuhiro Matsumoto)
Solution:   Only use line drawing characters when 'ambiwidth' is "single".
            (Ken Takata, closes #4477)
