# It solves a problem occurring with nested links (i.e.
# "outer text gfm ref more outer text"). This will not be
# interpreted as intended. Browsers will parse something like
# "outer text gfm ref 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.
# "outer text gfm ref more outer text").
