The `...` is referred as the historical syntax in all sources that I
managed to find. The $(...) is the new and improved syntax. As long
as we use /bin/sh I think we should not assume that it is capable of the
new syntax.

$ uname -a
SunOS sole 5.10 Generic_118822-11 sun4u sparc SUNW,Sun-Blade-1000
$ thisyear="$(date +%Y)"
$ echo $thisyear
$(date +%Y)

As far as I understand .\? will match a single char (any char) or no char
at all so if we have (output of "ar tv"):

-rw-r--r-- 1 0 0      4 Oct 16 18:30 2005 debian-binary

so with your regex \(.\?\) matches the space character between
16 and 18:30. I don't see how this help with regard to the problem
you are describing above ?!
