Yeah, that won't work, because there is no such option. We do have
"--prefix", but I suspect that's not flexible enough for what you want.

If you only need a single subdirectory with a custom prefix you could do
something like this (variables only used to keep the lines short):

	$ subdir=WebPortal/Templates
	$ prefix=myPath/myWeb/Templates/
	$ (cd "$subdir" && git archive --prefix="$prefix" HEAD) >my.tar

The output file can be specified with -o as well, of course, but you'd
either need to use an absolute path or add "../" for each directory
level you descend into (-o ../../my.tar in this case).

Couldn't you also do:

  git archive --prefix=$prefix HEAD:$subdir >my.tar

? I guess that loses the pax header with the commit sha1 in it, though,
because you are feeding a straight tree instead of a commit.

We didn't when git-archive was written, but these days we have
get_sha1_with_context to remember incidental things about an object we
look up. It should perhaps remember the commit (if any) we used to reach
a treeish, and then the above command line could still insert the pax
header.
