Set svn:special erroneously on a non-link multiline file (I think this is most
likely to happen in a mixed Windows/Unix setup):
svnadmin create repo
svn import -mm repo/README.txt file://`pwd`/repo/A/f
svnmucc -mm propset svn:special '*' file://`pwd`/repo/A/f
svn co file://`pwd`/repo wc
The code in create_special_file_from_stream will fallback to creating an
ordinary file but the file will only include the first line of content. The file
shows as status ~ on Unix, and reported to be status M on Windows although I
have not verified that. Creating the file is OK but it should include the full text.
