[clang-format] cannot insert space at end of line

using a current master build of qt-creator, i'm seeing one issue:

consider the code:

foo();

if the text cursor is at the end of the line and i press the space key, the space is not inserted. probably the clang-format plugin will re-run formatting and remove the inserted whitespace.

there seems to be a new option (format while typing), but that does not seem to be related. if i disable the clang-format plugin completely, the bug disappears
