Feature request: link to specific line or range of lines in deploy log

[junosuarez]

To aid in troubleshooting/discussing deployment logs, it would be great to be able to link to a specific section, like you can with github links e.g. by adding #L100 to go to line 100 of a file or #L100-115 to highlight lines 100 - 115.
