* generic/tclIO.c (CopyData): Applied another patch by Alexandre
* io.test (io-53.8a): Ferrieux <ferrieux@users.sourceforge.net>, * chanio.test (chan-io-53.8a): to shift EOF handling to the async part of the command if a callback is specified, should the channel be at EOF already when fcopy is called. Testcase by myself.
