mdocml: Polishing: * support -Ios= * create missing directories * fix

[schwarze]

Log Message:
-----------
Polishing:
* support -Ios=
* create missing directories
* fix output file permissions
* error out on comminication failures

I now consider this good enough for a first release.
Bugs and missing features are still likely, though.
