-* Remove command-line incompatibilities between GNU tar and UNIX tar
- as specified by UNIX98. The main problem is:
-
- l GNU tar doesn't cross filesystem boundaries.
- UNIX98 tar warns if all links cannot be resolved.
- (GNU tar --check-links option)
-
- Currently tar prints a warning when this option is used. Somewhere
- in the future its semantics will be changed to that of --check-links.
- In the meanwhile we should announce a phase-in period where "l"
- changes in semantics.
