As a longer explanation, this revision adds a new parameter to `system`
which changes to the given directory before executing the shell command.
This should make it easier to write often used constructs as shown below.
This example
system "cd ${worksrcpath} && touch foo"
can now be written as
system -W ${worksrcpath} "touch foo"
The new form has better readability in my opinion, especially with
syntax highlighting.
I called this new parameter `-W`, as there is the pre-existing `xinstall
-W` in our Tcl extensions which is similar.
