hgweb: extract entries() to standalone function There was some real wonkiness going on here. Essentially, the inline function was being executed with default arguments because a function reference was passed as-is into the templater. That seemed odd. So now we pass an explicit generator of the function result. Moving this code out of makeindex() makes makeindex() small enough to reason about. This makes it easier to see weird things, like the fact that we're calling self.refresh() twice. Why, I'm not sure. I'm also not sure why we need to call updatereqenv() to possibly update the SERVER_NAME, SERVER_PORT, and SCRIPT_NAME variables as part of rendering an index. I'll dig into these things in subsequent commits. Differential Revision: https://phab.mercurial-scm.org/D2815
