        REGRESSION (r86515): svn-apply ignores diffs that omit line count in chunk range
        https://bugs.webkit.org/show_bug.cgi?id=61162

        Fixes an issue where svn-apply may ignore a diff that contains a chunk range line
        that omits a line count. In particular, the chunk range regular expression does
        not match a chunk range line that omits a line count. GNU diff(1) will omit the
        line count in the chunk range if the line count is exactly 1. For example, appending
        a new line to the end of an existing file F that contains exactly one line of text will
        be represented in a diff with a chunk range line that omits the line count for F.

        * Scripts/VCSUtils.pm:
          (parseChunkRange): Added.
        * Scripts/webkitperl/VCSUtils_unittest/parseChunkRange.pl: Added.
        * Scripts/webkitperl/VCSUtils_unittest/parseDiff.pl:
          - Added unit test "Git: Append new line to the end of an existing file".
