Subject: [PATCH] Added  # to versionstring and strip comments

Prepended the version string with a # to avoid the CLI from interpreting
the version string as a command when pasting a dump file back (restore
in CLI).

Strip comments starting with `# comment` from lines. This is to allow
adding comments to CLI dumped backup files. For this i have an automated
addition of comments and/or manual comments by the user in mind.
