Some different, and more directly concerning, numbers:

In two months of serious development on one project, I have personally
cut 180 revisions, 1.7Mb (1.2Mb) of source code, and 1.2Mb (.6Mb) of
patch logs. Numbers in parentheses are excluding filesystem
overheads. A 1:2 ratio is not funny, especially since the source code
will probably stop growing at some point while the patch logs will
not. I've sampled two or three times already, and the ratio has been
about the same.

This problem is not going to go away on its own.

[That source code figure is actual bytes of hand-written
code. Including the autogenerated stuff that goes into a distribution
tree it's 3.3Mb (2.7Mb).]
