-Subject: [PATCH] Fix a regression in xmlGetDocCompressMode()
-
-The switch to xzlib had for consequence that the compression
-level of the input was not gathered anymore in ctxt->input->buf,
-then the parser compression flags was left to -1 and propagated
-to the resulting document.
-Fix the I/O layer to get compression detection in xzlib,
-then carry it in the input buffer and the resulting document
-
-  This should fix
