(feedback) spelllang detection

[sharethewisdom]

just a quick note: I use espeak and in call_say, I added

lang = self.vim.eval("getbufvar('%', '&spelllang')").split(',')[0]
if self.get_option(self.Options.USE_ESPEAK):
    args = ["espeak"]
    if lang:
        args += ["-v", str(lang)]
    ...

This works, but could obviously be improved.

I think this is a really cool simple plugin and I wish that it would also read errors and warnings whenever they appear. A few weeks ago, I asked a question about that.
