That would be perfect explanation except it does not work from command
line. :) So I assume this different kind of magic.

Invocation from command line gives:

$ darcs record --repodir=/home/radekg/private/runtime-EclipseApplication/TestProject
--all --patch-name=Name with space --skip-long-comment aaaaaaa.java

Recording changes in "aaaaaaa.java":

Non existent files or directories: "space" "with"
