in repository guile.

commit 7b1069269b14b24a52cc5b315b215f8691978165
Author: Mark H Weaver <address@hidden>
Date:   Thu Mar 26 23:13:47 2015 -0400

    Handle zero-length bytevectors correctly in (system base types).
    
    * module/system/base/types.scm (cell->object): Use 'get-bytevector-n'
      instead of 'get-bytevector-all', so that the zero-length case does not
      return EOF.
