Fail or warn about unsyncable files 

Filenames that MacOS sees as ending with .rdump or .idump are reserved
for resource fork and Finder info dumps. They are ignored on the HFS
side and complained about on the local side. This also applies to files
named underscore (_), which are reserved for directory Finder info.

Dotfiles are ignored on both sides (but warned about on the HFS side) to
make some modern tooling invisible to the MacOS.
