Paths with spaces, don't put single quotes around

When a file path has spaces, reposurgeon puts single quotes (') around. When using reposurgeon to build the git repository all is fine, but when using "git init; git fast-import <reposurgeon-out-file", the resulting path has single ticks around i.e. the first directory component starting with (') and the file name ending with ('). Not a severe problem but breaking "git fast-import".
