an issue that could cause false failure of sanity.sh

[Alexey Mahotkin]

There was an issue reported by users of cvs-nserver where test suite
would fail with 

  FAIL: basica-o1

The cause of this failure was existence of 'cvsadmin' group, and user
running make check was not in that group.  check.log shows:

PASS: basica-r5
** expected: 
cvs [a-z]*: while processing more than one file:
cvs \[[a-z]* aborted\]: attempt to specify a numeric revision
** got: 
cvs [admin aborted]: usage is restricted to members of the group cvsadmin
FAIL: basica-o1


I am not sure whether this is something to worry about (though I could
imagine situation where it could really bite someone), so I'm writing
this message to at least leave trail in archives.
