HTML email templates: restrict amount of visible hyperlinks Users report that some HTML email templates are confusing due to the large number of hyperlinks in them. They typically click the first thing they see that looks clickable without actually reading what they are clicking on, expecting that it all points to the same thing. In pullrequest invitations, the pullrequest and changeset URLs should be clickable, but the source and target repository should not: this is not what you typically want to see when taking action on this mail. Similarly in comment emails, the corresponding repository should not be clickable. Unfortunately, even if we remove the <a> hyperlink tags on these repository URLs, most mail clients will still recognize the text as being URLs and make them clickable anyway. Worse, they will do so in a different styling than the other links. Therefore, do add <a> tags in the HTML, but make use of styling like that of data_style, i.e. regular text color, grey background with dark grey border. The links _will_ thus be clickable but it will not be as inviting as before, thus removing confusion.
