Using 'smartcase' works halfway a sentence, so that when, for example,
you complete "Ne" the country name "Netherlands" matches, and not words
starting with "ne". But it's different at the start of a sentence. It
would require the smartness of spell checking to detect that. I'm not
sure if we would need to build in support for this, or that it can be
done with a plugin.
