[Bug-tar] [Patch] tar-1.20 - checkpoint.c

[Xavier Hienne]

Hello developers,

Please find attached a patch that fixes a bug in tar 1.19 and 1.20 which
makes the dot checkpoint-action not functioning and breaks backwards
compatibility.

# tar --checkpoint=.100
tar: .: unknown checkpoint action
tar: Error is not recoverable: exiting now

# tar --checkpoint-action=dot
tar: dot: unknown checkpoint action
tar: Error is not recoverable: exiting now

Bye

Xavier
