Fix nasty bracketing/precedence bug. Every time something read (and
refilled) a file that was either line- or un-buffered, all files were flushed. According to the code comment, the flush (according to ANSI) is supposed to happen on write + line buffered output files, not _all_ files. Obtained from: OpenBSD / Theo de Raadt, possibly from proven@cygnus.com
