------------------------------------------------------------+---------------
 The write_graphml function uses encode_char_entities from the
 property_tree::xml_parser.  This latter function does not behave properly
 when passed an empty string.

 I fixed this by modifying encode_char_entities to work properly in the
 empty string case.  I found this preferable to patching write_graphml to
 be aware of the limitation of encode_char_entities.

 Attached is a sample program that crashes on my system (Snow Leopard), the
 output and stack trace of that crash, and a patch to trunk r62110 which
 fixes the issue.
