The only thing then is what happens when you type backspace or left arrow to 
get back out to a previous indentation? If the TAB character inserts spaces, 
there's no problem going from left to right but it would seem more 
complicated to go back out again ie without having to type backspace 4 times 
and try to hope when outdenting more that I haven't typed backspace 23 times 
instead of 24 times by mistake thus not getting to the column I expected.

This is my only reason for wanting to keep tab characters in the text, and 
certainly it does give some disadvantages when trying to line up '|' '=' etc 
vertically - at the moment I admit my layouts do end up a bit contrived as I 
have to use more newlines to ensure I can use tabs only to accomplish the 
line-up...

So any solutions welcome :-)

Regards, Brian.
