 If you use the very first line of hints.txt file, as if you had a
 column ruleguide, you may notice that the output (expand-
 bug.txt)  never show the start of the sentence below the
 first five of the ruleguide.

Sorry, I don't follow.
http://mail.gnu.org/archive/html/bug-coreutils/2003-07/msg00012.html
contains this:

 [EMAIL PROTECTED] tmp]# expand -t1 hints.txt | cut -b1-9
 012345678
 1.  To co
 2.  The M
 3.  After
 4.  The s
 5.  To re
 6.  Refer

and this shows the start of the 6th sentence.  expand -t2 also
shows the start of the 6th sentence.  So I still don't see the bug.

Re: Bug in expand command.

That doesn't look like a bug to me.  For example, the first line
of hints.txt contains

1 . SPACE TAB T

so there are three columns before the tab, which means that expand -t1
and expand -t2 should behave the same.  Perhaps you didn't notice the
SPACE?

Bug in expand command.

[fzottola]

This is related to the expand comand's behaviour when you use it to
change tab
to spaces, and specifying two spaces per tab.

The point is, the spaces inserted for a 2 spaces/tab command are
actually the same as having specified 1 space/tab. And the difference is
observed when you specify 3 spaces/tab command, that expand performs right.

Comands issued to see the bug:

expand -t1 hints.txt | cut -b1-9
expand -t2 hints.txt | cut -b1-9
expand -t3 hints.txt | cut -b1-9

Attached are the files for testing the bug: hints.txt is a plain text
file, and expand-bug.txt is
a comand line record, so you can see what I saw.

I am using kernel 2.4.8-20 on a RH9.0 AMD K6/2 box.

Thanks for all.
