hgweb: stop using HTML comments in <script> Once upon a time, in 1995, there were browsers that didn't understand <script> tags and they would simply show the code inside as text. This started a tradition of wrapping everything inside <script> in <!-- HTML comments -->. Nowadays, it's not only not needed, but can be considered harmful[1]: - within XHTML documents, the source will actually be hidden from all browsers and rendered useless - `--` is not allowed within HTML comments, so any decrement operations in script are invalid [1]: http://www.javascripttoolbox.com/bestpractices/#comments
