Pkg.update() does not respect --startup-file=no

[baggepinnen]

When transitioning from Julia v0.5 to v0.6, I find it useful to start julia v0.6 with the --startup-file=no flag. This works alright until I do for instance Pkg.update(), in the end of which julia tries to load the startup file, which in my case causes an error to be thrown. My solution is to comment out everything in the file, which is a bit awkward.
