Aider has written 7% of its own code

The aider git repo currently contains about 4K commits and 14K lines of code.

Aider made 15% of the commits, inserting 4.8K and deleting 1.5K lines of code.

About 7% of the code now in the repo is attributable to an aider commit using git blame. This number is probably a significant undercount, because periodic reformatting by black is likely obscuring aider's authorship of many lines.

Here's the breakdown of the code aider wrote in the current code base according to git blame.
