I agree that it is unwise to overload the pathspec for this purpose.
Perhaps bulk of the documentation of a project is in javadoc in its
source code and extracted into some directory, where the user would
want to include untracked things as well as tracked ones, while
untracked contents of other directories are all not meant to be
packaged.  As "git archive" is primarily about freezing the contents
of a set of paths in a single revision into an archive, and
including untracked things is secondary, perhaps the right way to do
so would be to:

 (1) leave pathspec as-is---they mean "only this area of the named
     revision goes into the resulting archive", and 

 (2) introduce a new "--add-untracked=<wildmatch>" option, that can
     be multiply given, is cumulative, and is used to specify which
     untracked paths to be included in the result from the working
     tree contents.

So

	git archive \
		--add-untracked=./configure \
		--add-untracked='Documentation/**/*.html' \
		--add-untracked='Documentation/*.[1-9]' \
		HEAD -- . ':!contrib/' ':t/'

might be a way to package up sources we use without tests but
include the built documentation files.
