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>”).
