I was going to post an alternative theory but on more thought I think
Steven is right here.
od -c me.txt
show you? TABs or multiple spaces?
ls -ld me.txt
tell you about the file size? Is it 6 bytes long (three letters, two
TABs, one newline)?
Steven hasn't been explicit about it, but some editors will write spaces when
you type a TAB. I have configured mine to do so - it makes indentation more
reliable for others. If I really need a TAB character I have a special
finger contortion to get one, but the actual need is rare.
So first check that the file really does contain TABs.
