Subject: patch 7.4.1007
X-Git-Tag: v7.4.1007
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=e3303cb0817e826e3c25d5dc4ac10b569d0841e1;p=vim

patch 7.4.1007
Problem:    When a symbolic link points to a file in the root directory, the
            swapfile is not correct.
Solution:   Do not try getting the full name of a file in the root directory.
            (Milly, closes #501)
