I've noticed in various repos that the .hgignore files include variations on webrev, ^webrev/, or leave it out completely. In other words, it's inconsistent.

In:

which add your own personal .hgignore file, but that means everyone has to do it. A simple cleanup of webrev/.hgignore might be a good idea:

+ ^webrev/
+ ^webrev.zip
