Update of /b/source/CVS/src/sys/kern
In directory sun-lamp.cs.berkeley.edu:/d/users/mycroft/src/sys/kern

Modified Files:
	tty.c 
Log Message:
Fix a bug I introduced in the last commit, regarding a VTIME timeout causing
EWOULDBLOCK to be returned rather than looping again to see if any characters
are pending.  Also, fix another bug in the original code; if someone changed
VMIN behind our back, last_cc might be uninitialized when we reference it.
