I have read in many places that \t is a metacharacter for tab in regular 
expressions - but maybe that's only for sed, perl, awk etc...

Because that starts up auto-complete. In other words, I don't know how to 
insert a literal tab into a command line.

But I do not like that idea for scripts either - it can be difficult to 
visually discriminate a tab from a space character, which can too easily 
lead to errors.
