Blame command for Mercurial (HG) is partial
-------------------------------------------
Key: SCM-603
URL: http://jira.codehaus.org/browse/SCM-603
Project: Maven SCM
Issue Type: Bug
Components: maven-scm-provider-mercurial (hg)
Affects Versions: 1.4, 1.3
Reporter: Fabien
Attachments: HG_blame_command.patch
I use blame command for Mercurial provider (HG) and there is this exception :
{code}
Caused by: org.codehaus.plexus.util.cli.CommandLineException: Error inside
systemOut parser

{code}
This exception seems to launch when a line is empty in source file.
On version 1.3, blame is partial and no exception is launched.
I propose a patch to fix this problem.
