startup.jl location

[dwarfmaster]

All the documentation, the manual and the --help options indicates that the startup.jl file is loaded from location ~/.julia/config/startup.jl, while in fact it is influenced by the JULIA_DEPOT_PATH environment variable. I believe the documentation should be updated, as it is quite surprising. While I understand that it would make the documentation more heavy, it should at least appear when running julia --help with the right path.
