* generic/tclIO.c (Tcl_SetChannelBufferSize): Lowest size limit
* tests/io.test: changed from ten bytes to one byte. Need for this
change was proven by Ross Cartlidge <rossc@cisco.com> where
[read stdin 1] was grabbing 10 bytes followed by starting a child
process that was intended to continue reading from stdin. Even
with -buffersize set to one, nine chars were getting lost by buffer
size over reading for the native read().
