[PATCH 0/6] {maint} xslt and other improvements

[Theophile Ranquet]

The previous enhancements of DOT graphs only applied to those made via
Bison's --graph option. However, such graphs may also be made via XSLT
processing on the output of --xml option. DOTs obtained with this second
method are now equivalent to those obtained with the previous one.

The order in which the reduction edges appear is different, but there is no
difference between the sorted files. The maintainer-xml-check passes.

There are still occurrences of graphviz attributes not being in the best order
(which would be label first, then the other attributes alphabetically).

Theophile Ranquet (6):
  output: capitalize State
  xml: documentation
  graph: fix a memory leak
  xml: factor xslt space template
  xml: match DOT output and xml2dot.xsl processing
  tests: close files in glr-regression
