I had no idea (we really lack documentation on this), but some history digging shows this:

  commit 7595e2ee6ef9b35ebc8dc45543723e1d89765ce3
  Author: Junio C Hamano <junkio@cox.net>
  Date:   Sat Nov 25 00:07:54 2006 -0800

      git-shortlog: make common repository prefix configurable with .mailmap
      
      The code had "/pub/scm/linux/kernel/git/" hardcoded which was
      too specific to the kernel project.
      
      With this, a line in the .mailmap file:
      
          # repo-abbrev: /pub/scm/linux/kernel/git/
      
      can be used to cause the substring to be abbreviated to /.../
      on the title line of the commit message.
      
      Signed-off-by: Junio C Hamano <junkio@cox.net>

It apparently serves to abbreviate commits coming from pull requests, with a subject like

  Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux
