Pub should respect ~ in paths set in command-line arguments

[sethladd]

This command: pub install --sdkdir=~/Code/Dart-git/dart/xcodebuild/ReleaseIA32/dart-sdk/

Generates this error:
Package unittest not found in source "sdk".

I need to fix it by specifying the exact path:

pub install --sdkdir=/Users/sethladd/Code/Dart-git/dart/xcodebuild/ReleaseIA32/dart-sdk/

The --sdkdir command line argument isn't used anymore.
