mingw: follow-up to "replace isatty() hack"
The version of the "replace isatty() hack" that got merged a few weeks ago did not actually reflect the latest iteration of the patch series: v3 was sent out with these changes, as requested by the reviewer Johannes Sixt: - reworded the comment about "recycling handles" - moved the reassignment of the `console` variable before the dup2() call so that it is valid at all times - removed the "handle = INVALID_HANDLE_VALUE" assignment, as the local variable `handle` is not used afterwards anyway Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Reviewed-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
