-* 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)
-
- Perhaps we could announce a phase-in period where "l" changes in semantics.
- In the meanwhile we could make the "l" semantics to be determined by the
- value of POSIXLY_CORRECT variable.
