hgweb: fix jshint issues in mercurial.js

Everything is pretty self-explanatory except the last hunk, where jshint
complains: "Misleading line break before '||'; readers may interpret this as an
expression boundary."

There is a tweakable called "laxbreak" that allows line breaks before
operators, but I think it's fine to simply join this one line and avoid extra
config for now (we can cook up and add a sensible .jshintrc later).
