#272 misuse of link: tag

[CNCdreamer]

asciidoc implicitly knows how to deal with explicit URLs, at least those with the protocol identifiers http: and mailto:

Hence, there is no need to markup these URLs with the link: tag as occurs in the following 2.5 docs/src files

./common/userforeword_fr.txt:sur link:[http://fr.wikipedia.org/wiki/Philosophie_d%27Unix,
./common/Getting_EMC_de.txt:link:[https://lists.sourceforge.net/lists/listinfo/emc-users,emc-users mailing list]
./common/Getting_EMC_de.txt:link:[http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl,wiki.linuxcnc.org]
./common/Getting_EMC_es.txt:link:[https://lists.sourceforge.net/lists/listinfo/emc-users,emc-users mailing list]
./common/Getting_EMC_es.txt:link:[http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl,wiki.linuxcnc.org]
./common/Getting_EMC.txt:link:[https://lists.sourceforge.net/lists/listinfo/emc-users,emc-users mailing list]
./common/Getting_EMC.txt:link:[http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl,wiki.linuxcnc.org]
./common/Getting_EMC_fr.txt:link:[https://lists.sourceforge.net/lists/listinfo/emc-users,emc-users liste de diffusion].
./common/Getting_EMC_fr.txt:link:[http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl,wiki.linuxcnc.org]
./quickstart/stepper_quickstart_de.txt:at link:[http://wiki.linuxcnc.org].
./quickstart/stepper_quickstart_es.txt:at link:[http://wiki.linuxcnc.org].
./quickstart/stepper_quickstart.txt:at link:[http://wiki.linuxcnc.org].

Using the link: tag just adds more non-functioning hyperlinks in the pdf format.

In any case a number of these instances are malformed.
