parse-datetime: fix crash or infloop in TZ="" parsing This was reported in http://bugs.gnu.org/16872 from the coreutils command: date -d 'TZ="""' The infinite loop for this case was present since the initial TZ="" parsing support in commit de95bdc2 29-10-2004. This was changed to a crash or heap corruption depending on the platform with commit 2e3e4195 18-01-2010. * lib/parse-datetime.y (parse_datetime): Break out of the TZ="" parsing loop once the second significant " is found. Also skip over any subsequent whitespace to be consistent with the non TZ= case. * tests/test-parse-datetime.c: Add test cases for TZ="" parsing.
