Subject: [PATCH] Fix tab erroring with "Unbalanced parenthesis" in
 erlang-shell .

From the github issue: https://github.com/erlang/otp/issues/8569

  This bug is caused by the code for erlang-calculate-indent, which calls
  erlang-beginning-of-clause to move to the beginning of the previous clause
  in order to calculate the appropriate indentation.

  If erlang-shell was just started, this causes the point to move before the
  beginning of the first prompt, to the Eshell version string

  (Eshell V15.0 (press Ctrl+G to abort, type help(). for help)).

  Then, erlang-partial-parse is invoked, which results in a parse error
  giving rise to the message.
