FYI, emacs.git repo size: now 155M, was 1.1G

[Jim Meyering]

FYI, I just checked on the emacs.git repository
and found it to be unexpectedly large at over 1 GiB:

    $ du -sh .; git gc; du -sh .
    1.1G    .
    Counting objects: 539769, done.
    Delta compression using up to 4 threads.
    Compressing objects: 100% (127621/127621), done.
    Writing objects: 100% (539769/539769), done.
    Total 539769 (delta 423801), reused 524422 (delta 411781)
    Removing duplicate objects: 100% (256/256), done.
    155M    .

So I ran git's garbage-collector and that brought the size down to 155M.

Note that if your own emacs/.git/ directory is larger than say 200M,
you too can save some space by running "git gc".
