SnipMate-style snippets set the `abbr` (they call it `name`) via
the snippet line. Note: If both styles are used, then neosnippet
style wins.
Example of SnipMate-style:
snippet if if ... end
if ${1:condition}
${2}
end
Example of neosnippet-style:
snippet if
abbr if ... end
if ${1:condition}
${2}
end
