hgweb: use a function expression for the install listener of followlines UI We define the listener of document's "DOMContentLoaded" inline in registration and use a function expression (anonymous) with everything inside. This makes it clearer that this file is not a library of JavaScript functions but rather an executable script. (Most of changes consists of reindenting the "followlinesBox" function, so mostly white space changes.)

formatter: use templatefilters.json() Now _jsonifyobj() is identical to templatefilters.json(paranoid=False).

templatefilters: use list comprehension in json() Not important, but the code slightly looks better.

templatefilters: unroll handling of None/False/True It doesn't make sense to use a dict here.
