[xml] man pages have "$Date$" instead of real date

[Petr Sumbera <petr sumbera oracle com>]

Hi,

this seems to be wrong:

$ grep Date libxml2-2.9.0/doc/*.1
libxml2-2.9.0/doc/xmlcatalog.1:.\"      Date: $Date$
libxml2-2.9.0/doc/xmlcatalog.1:.TH "XMLCATALOG" "1" "$Date$" "libxml2" 
"xmlcatalog Manual"
libxml2-2.9.0/doc/xmllint.1:.TH "XMLLINT" "1" "$Date$" "libxml2" ""

I would expect instead of $Date$ some real date string. Not sure how 
this shall works but $Date$ is not translated by xsltproc..

Any idea?

Petr
