Full marks Jo! I guess that's "perldoc -q tabs".  

Good work... however :)  what I'm _REALLY_ curious about is a bash cl 
workaround "wrapper" for an in-place edit for those cl tools what don't have 
that feature. Here's what I finally came up with...

for file in *.[ch]; do expand -t 4 $file > t1; mv t1 $file; done

which _seems_ to have worked OK (I have backups!).

Regards,
Michael.
