-And fix for patch, Jul 28.
+Patch for :filetype completion. (Dominique Pelle, Jul 28)
 
 Windows 7: "Open with..." menu starts Vim without a file.
 
 Windows 7: installing Vim again doesn't find the previously installed Vim.
 
+Move more common code from if_python.c and if_python3.c to if_py_both.h
+
+Add filetype completion to user commands. (Christian Brabandt, 2010 Jul 26)
+But call it "filetype" instead of "syntax"?
+
 ftplugin/mupad.vim should not source AppendMatchGroup.vim, it should use an
 autoload function.
 Same for indent/GenericIndent.vim
