Allow `##` in commented_code_linter?

In emacs ESS, `##` starts a commented line, while `#` starts a comment at the end of a code line. This is convenient for auto-indentation (`## comments` do not indent, while `# comments` automatically indent).

Lintr considers `##` to start a comment as a mistake. Would it create other issues down the line to add `##` to the commented_code_linter?
