>Description:
The ':'-operator fails for certain regular expressions (see below).
Due to this failure several scripts of the cnews-distribution
(eg. upact and recovact) produced an corrupted active file with
one missing field. It took me some time to isolate the problem and
to recover all the news data...

>How-To-Repeat:
[/usr/lib/news] root % expr "1111111111" : '.*\('$dots'\)$
'
1111111111
[/usr/lib/news] root % expr "0000000000" : '.*\('$dots'\)$
'

[/usr/lib/news] root % 

>Fix:
As I don't have any more time to have a look at the sources, I will
install /bin/expr from the 2.0.5 distribution, wich worked correctly.
