" any leftovers are cleared.

" Set up the connection between FileType and Syntax autocommands.
" This makes the syntax automatically set when the file type is detected.
" Avoid an error when 'verbose' is set and <amatch> expansion fails.

" Execute the syntax autocommands for the each buffer.
" If the filetype wasn't detected yet, do that now.
" Always do the syntaxset autocommands, for buffers where the 'filetype'
" already was set manually (e.g., help buffers).
