Subject: ~p causes 'cu'/'tip' to crash   (#68)
Index:	usr.bin/tip/cmds.c 2.11BSD

Description:
	Using the  ~p command to "put" a file to a remote system
	causes a segmentation violation.

Repeat-By:
	'cu' to a system and use ~p to transfer a file.  The [put] prompt
	appears.  Enter the filename followed by a return and observe
	the segmentation violation.

Fix:
	The local variable "copynamex" conflicted with the global buffer
	"copyname".  Renaming the "copynamex" to "cpynamex" to make it 
	unique fixed the problem.

	Apply the patch below and reinstall 'cu'.
