[arch-dev-public] [signoff] expat-2.0.1-4

Jan pointed out another issue that needed patched in expat so here goes -4. ChangeLog: Add fixes for CVE-2009-3560 (in -3 previously in [testing]) and CVE-2009-3720. CVE = security issue so is there any chance I can get more that one signoff in two days this time? Allan
