Ok, correction, sorry. Upon discussion on the libstdc++ we now agree that in
fact the correct output is:
val: -123456 fmt: *(1,234.56)
lval: -123456 fmt: *(1,234.56)
That is the space is required and the fill char '*' must be used for it.
(once again, however, correctly no symbol must be output since showbase is false
by default).

Analyzed.
State-Changed-From-To: open->analyzed
State-Changed-By: paolo
State-Changed-When: Sat Feb 16 16:15:42 2002
State-Changed-Why:
The symbol is correctly missing in the formatted output
because, by default, showbase is false.
Similarly, the asterix does not show up because, by default,
width is 0 (see 22.2.6.2.2 for details)
However, your testcase shows a bug in the current code:
val: -123456 fmt: (1,234.56)
^
a spurious space here!
Patch in progress.
Thanks, Paolo.

>Description:
According to "The C++ Standard Library" page 713-714 by Josuttis
-123456 should be formatted as $"space"(1234.56) by the following program
tmput. The symbol, the dollar sign, is missing in the formatted
output.
According to Josuttis: "Where a space character has to
appear, the character fill is inserted." If I understand this
correctly, an asterix should be used as the space character in the
formatting pattern.
