Replace all but 3 occurences of StringSliceVar to StringArrayVar. This will
prevent the flag parser to interpretate the given values as CSV string.
Both --tag, --keep-tag and --path can be given multiple times, the command will
match snapshots matching ANY of the tags/paths. Only when a value is given which
contains a comma separated list of tags/paths, ALL elements need to match.
As we cannot reliably detect in advance if we can set ownership, permissions,
timestamps or ext attributes, execute ALL the requested changes before
returning the first error we found.
Report total errors at end of restore and stop printing entire stacktraces
where just the error message is sufficient.
Fixes#655
This is a new error which implements the restic.Fataler interface.
Errors of this type are written to stderr, the restic exits. For all
other errors, restic prints the stack trace (if available).
