duplicate ressource path information when using single file validation

PROBLEM:

When single file validating a specific ressource, the path information is 
displayed twice on ERRORs and WARNINGs:

$ java -jar epubcheck-3.0.2-SNAPSHOT.jar 
/Users/tobiasfischer/Entwicklung/epubcheck-svn/trunk/src/test/resources/30/singl
e/xhtml/invalid/issue230.xhtml -mode xhtml -v 3.0

Epubcheck Version 3.0.2-SNAPSHOT

WARNING: 
/Users/tobiasfischer/Entwicklung/epubcheck-svn/trunk/src/test/resources/30/singl
e/xhtml/invalid/issue230.xhtml/: File is validated as a single file of type 
xhtml and version 3.0. Only a subset of the available tests is run.
ERROR:

unk/src/test/resources/30/single/xhtml/invalid/issue230.xhtml(9,37): Undefined 
property: acknowledgements (use notation 'acknowledgments' instead)

Check finished with warnings or errors

EXPECTED:

ERROR: 
/Users/tobiasfischer/Entwicklung/epubcheck-svn/trunk/src/test/resources/30/singl
e/xhtml/invalid/issue230.xhtml(9,37): Undefined property: acknowledgements (use 
notation 'acknowledgments' instead)

OR:

ERROR: issue230.xhtml(9,37): Undefined property: acknowledgements (use notation 
'acknowledgments' instead)

PLATFORM:

Tested with 3.0.1 and 3.0.2-SNAPSHOT (r507)

ADDITIONAL INFO:

For EPUB file validation the absolute path information is cut off in 
ERR/WARN/HINT messages:

HINT: issue225.epub/EPUB/lorem.xhtml(21,36): Link attribute with no value

even if the path is absolute.
Don't know whether we should do it the same way for single file validation and 
display the filename only...
