"burn" does not handle deletion of tabs correctly. (revision 877)

[arshad.super@…]

If a tab(TAB_WIDTH=8) is input on the cmd line, the
buffer which tracks the cmd line input, does not increment
the count by TAB_WIDTH size. Now when backspace is used
instead of decrementing by TAB_WIDTH size it just decrements 1.

This results in short deletion when ever the tab is used.

I have modified, user/burn/main.c which fixes the above mentioned defect. Modified user/burn/main.c attached.

Version checkout : Revision 877.

Actually, the latest revision of burn includes tab completion, which means the backspace and deletion case is appropriately handled now. Thanks for your attempt at fixing it however.
