vim, tabs, and copying text

[Torquil Macdonald <torquil@frisurf.no>]

I have the following problem with vim inside an xterm:
If I write a file with a TAB at the start of each line in VIM, and try to copy 
and paste it, with the mouse, into another VIM running in another xterm, I 
get one extra TAB for each line like this:

	lkk
	kh
	kjh

becomes

	lkk
		kh
			kjh

I also get this when copying from other programs into VIM. Any ideas?
