protractor --specs mySpec.js myConf.js runs mySpec + specs[1..n] in myConf.js

[imbroglioj]

I am assuming that
protractor --specs mySpec.js myConf.js
means to run only mySpec.js using the defaults from myConf.js for everything else.

In fact, if myConf.js config.specs is an array with more than one spec protractor will replace the first spec with mySpec.js and leave the rest of the array untouched.

The only workaround I can find is to specify everything from myConf.js as a command line argument, which is not ideal. (Or to always specify all the specs on the command line and leave conf config.specs empty)

to Test:
conf.js: specs: ['spec1.js', 'spec2.js']
command line: protractor --specs spec3.js conf.js
==> will run ['spec3.js', 'spec2.js']

This error will be hidden if you specify specs on the command line equal in number to or greater than are in conf.js

Cause: runner.js#merge (line 48 in release 0.13.0) handles Array as an Object, which is fine for extending the array, but does not work if the array should be shortened.

Let me know if more info is needed, or if I'm misunderstanding the intent of the --specs arg.

Good catch, this is indeed undesired behavior.
