[PATCH v2 0/2] Explicitly fflush stdout in git clean

This is yet another patch that was funneled through a Git for Windows PR, read: it has been battle-tested.

Of course, the current iteration of this patch series has not been battle-tested, so please do review carefully, so that we can prevent bugs from slipping in during the review process.

Changes since v1:

 * Added a preparatory patch that refactors all interactive input reading
   via strbuf_getline(..., stdin).
 * Adjusted the patch and its commit message accordingly.

Johannes Schindelin (1):
  Refactor code asking the user for input interactively

  Explicitly `fflush` stdout before expecting interactive input
