Should detabify 8-character tabs.

[Lachlan Andrew]

Greetings,

It seems that DDD's treats 8-character tabs as width-1 characters when
the mouse pointer is used to select text or display a value.

This seems puzzling, since this case is singled out in tabs.h as the
only case which is not "detabified".  I would think that the simplest
fix is just to detabify this case as well.  (Use  tabs.H  below
instead of  tabs.h  from 3.3.1, downloaded 14 July 2001)  Unfortunately,
I haven't yet been able to get  ./configure  to finish, so I haven't
tested this patch, but it looks pretty safe...

This is a **fantastic** program -- for ages while I was using  xxgdb
I kept wishing for something like this!  Keep up the good work!

Regards,
Lachlan
