Inside parentheses, line-initial commas align with the open parenthesis

For example:

  [ one
  , two
  , three
  ]

This does not affect coding styles that don't put commas at the
beginning of lines.

tools:
In Emacs it is possible to remotely edit a file, by opening for
example /ssh:somehost.com:/path/to/file.erl.  In Emacs, the feature
that makes this possible, is called TRAMP.  When compiling such a file,
by typing C-c C-k, an inferior Erlang shell is opened on the remote
host, but the compilation expression that was evaluated in the remote
Erlang shell was:

   c("/ssh:somehost.com:/path/to/file", [...]).

which resulted in a "no such file or directory" error.
This commit changes the compilation expression into:

   c("/path/to/file", [...]).

for files opened remotely via TRAMP.  The file name is adjusted
similarly when compiling .yrl and .xrl files.

In a buffer opened remotely, the Elisp function buffer-file-name
returns the full path with TRAMP syntax.  In this example it would
be "/ssh:somehost.com:/path/to/file.erl".  A new function,
erlang-local-buffer-file-name, has been introduced, which peels off
the TRAMP syntax on remotely opened files, while for locally opened
files, it just calls buffer-file-name.
