git-svn reads passwords from an interactive terminal or by using GIT_ASKPASS helper tool. This cause GUIs (w/o STDIN connected) to hang waiting forever for git-svn to complete (http://code.google.com/p/tortoisegit/issues/detail?id=967). Commit 56a853b62c0ae7ebaad0a7a0a704f5ef561eb795 also tried to solve this issue, but was incomplete as described above. Instead of using hand-rolled prompt-response code that only works with the interactive terminal, a reusable prompt() method is introduced in this commit.
