Comment (by Cigaes):

 Spaces in file names is a very bad idea in many situations. The concat
 demuxer is very conservative by default; implementing fine-grained
 policies would be way beyond its scope, and not everybody has the same
 needs as you.

 If you get file names from untrusted sources, you need to validate them
 according to your specific security requirements.
