Subject: Automatic capitalisation at beginning of sentences

Keep track of end-of-sentence characters while typing and automatically
enable shift when appropriate.

The last few characters just before the cursor need to be queried in
some cases: Begin of input, cursor has moved or text is deleted.
This might have a performance cost.

This normally only enable shift but it also needs to disable shift when
the cursor moves.
