This is a reaction to patch590 and patch609.

Currently:

darcs init
mkdir d
# add lots of files
darcs add d/non-existent d/*

# FAILS on non-existent file and aborts add (actually, crashes)

Proposed behaviour:

# Succeeds on all the files that *do* exist, but tells you about the 
files that failed (but in a way that doesn't scroll by)

NOTE: the behaviour proposed may be wrongheaded.  One risk may not 
notice that something went wrong.  Keeping in mind a sort of Eric-guess 
about people: nobody reads unless they are really forced to.

Oh, and we should fail if all adds fail, but not if no adds were specified

I think the exit code should be non-zero if any adds fail.

I agree with Ganesh (exit code should be non zero if one add fails).
