The way templates are searched is inconsistent.
For the templatetags the comments/%s/%s/<template>.html style is used while in the views the comments/%s_%s_<template>.html is used.
This should be consistently comments/%s/%s/<template.html imho.

Seems my svn diff doesn't generate valid patches.. I'll see if I can fix it.
(In ) Fixed #12600 -- Added some extra search paths for comment preview templates, allowing for naming parity with other templates in comments and admin. Thanks to hvdklauw for the report.
