Fixed two problems. Both are from condor-support. #2036: Fixed a crash when a ClassAd has more than one attribute and        an attribute  other than the first has an && with no second expression. #1881: ClassAds with multiple semicolons in a row used to cause a parse        error because an empty expression was not allowed. I saw no harm in        allowing them, so extra semicolons are now allowed.
