Parsing blame fails on invalid row

[juho-turunen-tampuuri]

For some reason for on of our repositories hg blame produces a row without any user or changeset infromation. Sonar-scm-mercurial fails on this row and throws away the whole analysis.

This might be a problem with mercurial but I would still prefer that such errors would be skipped and the analysis and available scm information sent to SonarQube server.

The offending part of blame output seems to be this. Notice the line with single curly brace

                               user1 1a25faa8b304 Tue Apr 17 07:26:46 2007 +0000:

        }

Error we've got is this
