For what it's worth, the sizes of the key git dirs on my box:

dmd.git == 4.4 - 5.9M (depends on if the gc has run recently to re-pack 
new objects)

druntime.git == 1.4 - 3.0M

phobos.git == 5.1 - 6.7M

The checked out copy of each of those is considerably more than the packed 
full history.  The size, inclusive of full history and the checked out 
copy, after a make clean:

dmd       15M
druntime   4M
phobos    16M

Ie, essentially negligable.
