[issue2643] Cannot use --config k=v in an alias

[Jesse Glick]

New submission from Jesse Glick <jesse.glick at oracle.com>:

In reference to issue1906, I cannot use

[alias]
outdiff = out --verbose --config diff.ignorews=1 --patch

or I get

abort: option --config may not be abbreviated!

Not clear why this would be an error, other than that certain config options
(not this one) could affect earlier stages of command processing.

The following patch against 1.7.5 seems to allow it, though I am not sure
what other problems might be introduced:

diff --git a/mercurial/dispatch.py b/mercurial/dispatch.py
