link_to_gfm(body, url, html_options = {}) Link

Use this in places where you would normally use link_to(gfm(…), …).

It solves a problem occurring with nested links (i.e. “<a>outer text <a>gfm ref</a> more outer text</a>”). This will not be interpreted as intended. Browsers will parse something like “<a>outer text </a><a>gfm ref</a> more outer text” (notice the last part is not linked any more). #link_to_gfm corrects that. It wraps all parts to explicitly produce the correct linking behavior (i.e. “<a>outer text </a><a>gfm ref</a><a> more outer text</a>”).
