commit e70e5b4238f37e144a34b8b724d010d37d2baa93
Author: Jay Doane <ja...@apache.org>

    Relax xref ANNO limitation
    
    Currently this xref interface assumes an ANNO format of a single line
    number, but versions of OTP > 23 return a tuple, resulting in a an
    error like:
    
    ERROR: xref failed while processing /Users/jay/repos/couchdb/src/snappy: {'EXIT',
     {{badmatch,
       [{attribute,{1,1},file,{"src/snappy.erl",1}},
    
    This relaxes the assumption on any particular ANNO format and accepts
    them all.
