You do not need any :exe here in the current state. But you need :exe in
the first statement: do not ever use % in shell commands as it is not doing
any escaping. E.g. if name of currently edited file contains space first
line of function MD will not do its job.
You should use
execute '!pandoc" shellescape(@%, 1) '-o ' shellescape(expand('%:t:r'))
'.html'
instead. This does not apply to vim commands: :tabe %:t:r.html is fine.
