[PATCH] clean: flush after each line

["Orgad Shaneh via GitGitGadget" <gitgitgadget@gmail.com>]

From: Orgad Shaneh <orgads@gmail.com>

Some platforms don't automatically flush after \n, and this causes delay
of the output, and also sometimes incomplete file names appear until the
next chunk is flushed.
