In an xterm, it works:

% hexdump -C tabfile
00000000  61 09 62 0a                                       |a.b.|
00000004
% cat tabfile
a       b
% tabs 6
% cat tabfile
a    b

This doesn't seem to work on a system console though, the tabs command
fails with "tabs: terminal cannot clear tabs" and a return value of 1.
