Poll: what should happen when -delete fails?

[James Youngman]

A while back I implemented -delete for GNU find.  Some comments have
been made that its behaviour when it fails are somewhat unexpected.
I thought at the time that I made the right tradeoffs, but that might
not be the case.  Although there is a Savannah bug open for this
(https://savannah.gnu.org/bugs/?20802) please have a think about what
you would like to happen before you read about what happens juat at
the moment.


1. If unlink or rmdir fails, should the -delete action return true or false?

2. If -delete returns false because it fails, should find also return nonzero?

3. Should -delete issue a message on stderr if it fails, or (on the
other hand) should it be possible for the caller to choose how the
message is phrased by doing something like this?

\ ( -delete -o -fprintf /dev/stderr "No luck with %u's file %p\n" \)
