[erlang-questions] A style question

[Dale Harvey]

by default the emacs erlang mode will indent the anon function from the end
of the fun() -> line

mnesia:transaction(fun() ->
                           ... some code here ...
                   end),

this takes up 27 of your 80 characters, whereas F = fun() -> is only 12,
thats the main reason I stopped doing it.
