OK to push?

Thanks,
Ralf

    func_version copes with multi-line copyright headers.
    
    * libltdl/config/getopt.m4sh (func_version): Slurp in copyright
    lines until a period is found.
    * libltdl/config/ltmain.m4sh: Multi-line copyright is ok to use
    now.
    * tests/help.at (standard command line options): New file, new
    tests.  Make this test group the first one for libtool tests,
    moving the banner ...
    * tests/duplicate_members.at: ... from here.
    * Makefile.am (TESTSUITE_AT): Add tests/help.at.
