The problem is that in the defaults file you don't want quotes around the
command:

$ echo "ALL external-merge xxdiff -m -O -M %o %1 %a %2" \
       > _darcs/prefs/defaults

I've added mention of this to the documentation, and also added output
indicating what command is being run, and afterwards giving the exit code
(which isn't always zero, even when the command runs successfully).

Alas, I haven't been able to figure out why this bug happens--somehow the
merge directories are getting deleted for no reason I can figure out. :(
Even if you give an invalid external merge command, the pull should still
continue, but somehow the relevant directories are getting deleted. :(
