unison should handle socket "files" gracefully

[perlhead]

Binary package hint: unison

When unison encounters a socket "/foo/bar" while scanning replicas, it complains with "Error: path /foo/bar has unknown file type." A simple fstat() call would enable unison to know that it's a socket which can't be replicated in any useful way, and thus automatically ignore it!

or it will be good to have an option to ignore files with specific file types

and same thing for fifo (named pipe) file type :(
