156924 - Tab characters don't always align in compose window

Status: RESOLVED FIXED

In the plaintext editor with fixed width font, tab characters only position the
carat correctly on a line when there is non-whitespace following the tab.  If
the tabs are at the end of a line, they will position the carat short of the tab
stop.  If a non-whitespace character is typed at the end of the line, the tabs
will expand to their proper width.  

This is mostly an inconvenience when trying to build a table in the plaintext
editor. 

Reproducible: Always
Steps to Reproduce:
1. Open a mail composition window.
2. Type a couple of tabs in the message body
3. Notice that the carat doesn't move the same distance each time
4. Type a alpha character.
5. Notice that the carat jumps forward to position the character at the
appropriate tab stop

Actual Results:  The carat doesn't position itself on a tab stop until a
non-whitespace chacter is typed after the tab.

Expected Results:  The carat should always align on the next tab stop when a tab
character is inserted.

I'm surprised that this bug is still open.  I believe it was fixed when the similar bug 58712 was fixed back in 2002.
