Description of problem:
The tar man documentation indicates that "-l" and "--one-file-system" are one
and the same.  Unfortunately "-l" and "--check-links" are now one and the same.
 It would be a good idea to update the documentation, given such a dramatic change.

Version-Release number of selected component (if applicable):
tar-1.17-4

How reproducible:
Always

Steps to Reproduce:
1. select a filesystem with a mount point on it (eg /)
2. tar -c -l -f /somewhere/tarfile1
3. tar -c --one-file-system -f /somewhere/tarfile2
  
Actual results:
tarfile1 and tarfile2 are not the same. Step2 probably filled /somewhere to
overflowing.  But man documentation says:
>>     -l, --one-file-system
>>         stay in local file system when creating an archiv

Expected results:
man documentation should be accurate

Additional info:
Info documentation is great, but who has the time to read such voluminous
documentation? Some people prefer concise documentation such as man (if only the
GNU people could come to terms with this alarming concept).
