It was a request from Linus:

commit 3e8b5ddf17d4639d41bc57ecfb51633815b70e49
Author: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>
Date:   Fri Apr 27 16:44:56 2012 -0300

    perf annotate browser: Remove the vertical line after the percentages
    
    It is confusing when used with jump -> target lines.
    
    Requested-by: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx>

Make it configurable? Press 'S' and you get a separator? Linus?
