The standard of removing might be kind of arbitrary, but I think the remain new languages are all worth to add
BTW, I think we do not need to add all the xml files in the Extra-Source-Files section.
When you check out the source from the repository, you can now do 'make prep' to generate the syntax parsers from the xml definitions.
Two-letter class names are now used for default styles, and detailed lexical information is omitted unless the new OptDetailed option is specified. Also, the "Normal" style is no longer used, and spans are not used for "normal" markup. The result is significant compression of the highlighted source (in one test, 191K -> 72K). NOTE: you must update your highlighting CSS stylesheets to use the new two-letter identifiers. There are new versions of the three standard CSS files in the css directory of the source distribution. A new -d/--detailed option has been provided in the Highlight executable. This selects OptDetailed.
