The exact text is: "Unlike get, pull and push also work over ssh." in

These problems were my fault. The proj/ directory is comprised of a number of 
modules, each is a directory. I did darcs add modules/*/*.c and I missed or 
ignored the 'Skipping:' message because I had not added the modules parent 
directories (modules/*).

Cool. At least I wasn't imagining this too.

Writing a parser for a program in development can be troublesome, because 
there is no implicit contract regarding output, like there is with an API. 
But the --xml-output flag sounds like a good compromise (haven't tried it 
yet). I'll give it a whirl.
