Bug#968231: global: does not index definitions with pygments anymore

[Gregory Heytings]

Hi Punit,

The bug is a modification in gtags.conf:

 pygments-parser|Pygments plug-in parser:\
        :tc=common:\
-       :ctagscom=/usr/bin/ctags:\
+       :ctagscom=/usr/bin/ctags-exuberant:\
        :pygmentslib=$libdir/gtags/pygments-parser.la:\
        :langmap=ABAP\:.abap:\
        :langmap=ANTLR\:.G.g:\

When exuberant-ctags (which is not a dependency of global) is not 
installed, definitions are not indexed.
