45114: vcs_info quilt: Improve support for svn-style patch headers.

Browse source 
Additional lines between the |-separated header line and the actual
log message, as generated by 'svn log -v' and 'svn log -g', are now
supported.

This change affects you if you have quilt patches with 'svn log'-style
information in their headers, regardless of whether you use quilt
standalone, quilt over svn, or quilt over some other VCS.
