Correction of some minor HTML output issues

[fob]

Even in the latest comment-template.php I found some functions that use single quotes for the HTML output of links instead of double quotes. It works. But wouldn`t it be nicer to avoid a mix of notations in the source code? I personally prefer to use single quotes within functions and double quotes for the HTML output. However. Consistent code should be better than a mix of all. So I would like to suggest renewing some functions like:

• get_comment_author_email_link

( $return .= '<a href="mailto:'.$email.'">'.$display.'</a>'; )

• get_comment_author_link

( $return = '<a href="'.$url.'" rel="external nofollow" class="url">'.$author.'</a>'; )

• get_comment_author_url_link

( $return = $before.'<a href="'.$url.'" rel="external">'.$display.'</a>'.$after; )

and perhaps

• get_comment_reply_link
• get_post_reply_link

in order to output double quotes as they are used within most of the other functions that prepare links for the HTML output.

Single quotes are consistent with our coding standards:

We use them in HTML output in quite a few places, so I don't think changing them in one file would bring more consistency.

Hmmm... That`s interesting. Thank you for making your position clear to me.

It does indeed happen in many places, and there doesn't seem to be a very strong case for that kind of code churn.
