Bed version 1.0 patch #2.

[Stephen J. Muir]

System: Bed version 1
Patch #: 1
Priority: LOW
Subject: some editors confuse "bed"
From:	scott at cstvax.UUCP (Scott Larnach)

Description:
	If the text editor called doesn't put the file back into the original
	inode, then the program fails to recognise that the file has changed.

Fix:
	Run the command "patch < thisfile".
	If patch indicates that "bed.c" is the wrong version, you may need
	to apply one or more previous patches, or the patch may already
	have been applied.  See the file "bed.c" to find out what has or
	has not been applied.  In any event, don't continue with the patch.
