I've just added support for [^ \n\t] sort of delimiter to define tokens.

Currently this can be done on a per-repository basis using
_darcs/prefs/defaults. I haven't figured out the best balance for
supporting this sort of preference on a project basis (i.e. so changes to
it will be pulled via a patch).
I could make defaults behave like binary and boring, in that by default it
is determined on a per-repository basis, but allow you to make change which
file is used as the "defaults" file to be a version-controlled file... but
this starts getting a bit scary--allowing patches to change the
command-line parameters to darcs in a not-entirely-user-visible way opens
up a whole can of security worms (so if it gets done it'll be post-1.0).
So for the moment, you'll have to set your repository defaults by hand. Or
you could create a version-controlled file named darcs_defaults and add to
your makefile something like
cp $< $@
(it would be better to be a bit more clever and take into account the case
where the code is compiled from tarball and _darcs isn't present...)
