addremove: warn when addremove fails to operate on a named path

It looks like a bad path is the only mode of failure for addremove.  This
warning is probably useful for the standalone command, but more important for
'commit -A'.  That command doesn't currently abort if the addremove fails, but
it will be made to do so prior to adding subrepo support, since not all subrepos
will support addremove.  We could just abort here, but it looks like addremove
has always silently ignored bad paths, except for the exit code.
