GNU tar gets the file name byte-by-byte exactly as it is on-disk or as
it would be returned by readdir(). Shell-escaping was done properly.
Maybe tomorrow, I'll step through the sources again and spot the call
pathes where the problem actually arises.

But to draw the line, it should be enough to properly name the files
to be covered by the backup. I don't think there's anything in the
documentation telling me that uncommon file names need extra care
except proper shell quoting and (in case of leading '-') a separating
"--" or "./" prepended to make it "./-foo" to not look like an option.
