Inhibit electric newline after "->" when inside a type spec
The Erlang mode for Emacs inserts a newline after every "->", which saves you one keystroke when writing a function, but that is inappropriate when writing a type spec, as you'd normally keep the spec on one line. This change inhibits the automatic insertion when the current line starts with "-spec" or "-type".
