ngmin reformats code, e.g. comments

[raDiesle]

Hi,

for grunt-replace I used var config = "default";// REGEX_MATCHER
but ngmin will break myregex, because it will result in:
var config = "default";
// REGEX_MATCHER

ngmin should not reformat code, I think.

This isn't a duplicate? This says the comments gets moved, not _re_moved.
