Tokens are 1-based. Thus when we print tokens, we need to decrement the column number. This was done for resolver errors, but not for verification or parsing errors. In addition, parsing errors were inconsistent with resolution errors case-wise. Unfortunately, the fix affects the output of many tests. --- Source/Dafny/Parser.cs | 12 ++- Source/DafnyDriver/DafnyDriver.cs | 8 +- Test/dafny0/AdvancedLHS.dfy.expect | 2 +-
