# 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>").
