The format and layout of DartTestfile.txt files is left from an old
tcl-based implementation that provided a Dart client before ctest
(http://public.kitware.com/Dart).  It still needs to be supported so we
cannot change this layout for now.

We could probably make it supports spaces in test names though.  No one
has ever reported this problem or tried to use spaces before so it was
never implemented.

The VERBOSE variable tells *make* to report its rules verbosely and does
not control the way the rules are executed.  CTest should probably look
for that environment variable and enable the option though.
