Merge branch 'fix-terminal-prompt'

This fixes the issue identified in

	#1498

where Git would not fall back to reading credentials from a Win32
Console when the credentials could not be read from the terminal via the
Bash hack (that is necessary to support running in a MinTTY).

Tested in a Powershell window.
