Dependency on xorg7-* only on last package

Our gen-special.sh transforms a dependency on compound packages
(xorg7-*) on a dependency on the list of packages. This generates
a lot of trials when removing circular dependencies, because if the
dependency on xorg7-* is optional, all packages in the list are tried
in turn, while it is sure that anyway the dependecy must be eliminated.
If the dependency is only on the last package, the circular dep
is eliminated at first try.

4# generates an xsl stylesheet containing a template for special
5# cases in the book:
6# - If the version does not begin with a number, it is impossible to know
7# where the package name ends and where the version begins. We therefore
8# use the ENTITY at the beginning of the validated full-xml.
9# - If a package is part of a group of xorg packages (proto, fonts, etc)
10# there is no easy way to extract it from the xml. We use the ENTITY at
11# the top of each file x7*.xml
12# - Some non-versioned packages are needed as dependencies of others: we
13# attribute version 1.0.0 to them. It is just used to know if the package
14# is installed, by checking inst-version.
15# - If a package is versioned but the version is not mentioned in the book
16# (currently only udev), we retrieve the version by other means
17#-------------------------------------------------------------------------
18# Arguments:
19# $1 contains the name of the validated xml book
20# $2 contains the name of the ouput xsl file
21# $3 contains the name of the book sources directory
