* leoliu/tools/fix_edoc_mode:
  Fix font-locking for @deprecated in erlang-edoc-mode

The option makes it possible to customize the indention of
if/case/recieve patterns.

Before the change, the indentation of 'if' patterns is 3 steps and
'case' patterns is 4 steps.  It cannot be changed alone.  Some people
prefer other styles, for example, zero indentation.

case a of
true ->
   do_something();
false ->
   do_something_else()
end.

This patch just adds an option `erlang-icr-indent'. Its default value is
`nil' which means keeping the legacy behavior.  When non-nil, the
pattens of if/case/receive are indented according to
`erlang-icr-indent'.  "(setq erlang-icr-indent 0)" will keep
if/case/receive at the same column of the sub-clauses.

  Fix all whitespace-related issues in erlang.el

Continuation of the previous commit on test files, which gave
whitespace diffs for tabs vs spaces depending on personal settings.

And we want to encourage space instead of tabs.
