Drop support for Thai-XTIS, which was always non-standard and never used. lisp/ChangeLog addition: 2011-04-08 Aidan Kehoe <kehoea@parhasard.net> * unicode.el (load-unicode-tables): No longer include thai-xtis in the default Unicode precedence list. * mule/thai.el: * mule/thai.el (tis-620): * mule/thai.el (windows-874): * mule/thai.el ("Thai"): Move the Thai language environment and the TIS-620 coding system to this file; add support for Microsoft's code page 874. * mule/thai-util.el: * mule/thai-xtis.el: Remove these two files; XTIS was always non-standard and was never widely implemented, and we've never supported the character composition necessary for thai-util.el. * dumped-lisp.el (preloaded-file-list): Drop thai-xtis, dump thai.el instead.
