Hi,

   This isn't so much a perl question as it is a terminal question. The 
program is perl, but I am more interested in what the user's 
shell/terminal is doing. Ie: How can I ask the terminal, "Hey, how many 
spaces do you expand a tab to?". Like how you can use the shell program 
'tput' to ask the shell how many columns a current line has.
