[Patch] fhandler.cc: debug_printf when copied_chars is zero.

[Bas van Gompel]

Hi,

While going over a strace I noticed some garbage in the (debug) output
when fhandler_base::read had read zero bytes. Following (trivial)
patch fixes that.


ChangeLog-entry:

2004-12-05  Bas van Gompel  <[EMAIL PROTECTED]>

        * fhandler.cc (fhandler_base::read): Don't debug_printf garbage when
        copied_chars is zero.

L8r,

Buzz.

BTW: In how-vfork-works.txt, lines 31 and 32 end in CRLF.
BTW2: ansi.sgml has no linefeed at the end of the file.
