ClangFormat: Format more code while typing

With the extra option "Format while typing" checked try to format
text before the current position without breaking the current input.
To accomplish that we make proper choices which replacements to apply.

The advantage of this change is to decrease the need to manually
format code which is just written.

Some minor bugs are fixed during the testing of this change.
