Are you sure about this? This is not the tab problem I am familiar
with in the past. In the following sample, the columnar text labeled
'col2' should all be aligned at column 9:
x<tab>col2
xxx<tab>col2
<tab>col2
In the first line, the tab is replaced with 7 spaces, the second line
by 5, and the third line by 6. So tab replacement is a bit more
involved than simply "s/\t/ /g".
As I recall, the number of spaces to replace a tab by is something
like 8-(col % 8) where col is the column location of the tab with the
left most column being 0.
