It looks weird.

The whole point of the BufReadPost autocommand is to match
against a file name, in your case you use the wildchar * to match against
any file pattern, but within the autocommand, you only want to match
against .kshlib.

Secondly, your exe 'normal set ft=sh' is wrong, you missed the
colon and additionally you don't need neither the 'exe' nor the 'normal
command so this statement can be simplified to :set ft=sh.

Thanks.

After all your whole autocommand can then be simplified to
au BufReadPost *.kshlib :set ft=sh
which is basically the same autocommand, that is given below
:h new-filetype, except that you are still missing the BufNewFile
autocommand.

Christian
