[TxMt] Soft tabs / tabs <-> spaces

[Andy Armstrong]

Sorry if this has come up before and sorry if I'm missing something  
obvious...

I like to work with tab stops set to 4 characters and use spaces  
rather than hard tabs for indentation - otherwise everything gets  
messy when you process your file with something that expects 8 column  
tabs.

Something seems a little counter-intuitive with the soft tabs setting  
in TM. With Soft Tabs (Spaces) selected hitting tab still inserts a  
hard tab character. Additionally with Soft Tabs selected Text >  
Convert > Tabs to Spaces doesn't seem to do anything - it certainly  
leaves plenty of tabs in the files. With Soft Tabs turned off I still  
get hard tabs when I hit the tab key - but at least Tabs to Spaces  
works.

This is in Perl mode - I haven't tried other modes yet but shall if  
it's likely to make a difference.

So - what's the blindingly obvious solution I've missed? :)
