[Stefan Monnier]

branch: externals/marginalia
commit 7d3f01891d53b071ac70aa58f763442ebf7724cc
Author: Omar Antolín <omar.antolin@gmail.com>
Commit: Omar Antolín <omar.antolin@gmail.com>

    Add annotations for files and buffers
    
    These are not turned on by default.
    
    For files, use size and modification time.
    
    For buffers, modification status, file (if there is one) and major
    mode.
    
    These were imported from embark, per issue #3.
