I've done quite a few small corrections/improvements to the
D-tour's English. Almost all have been accepted.
However, four have not been accepted, apparently for technical
reasons. But I don't understand what's wrong or what I need to do
to fix them. (I'm not very knowledgeable about github.)
These are the ones that are held up:
https://github.com/dlang-tour/english/pull/336
https://github.com/dlang-tour/english/pull/335
https://github.com/dlang-tour/english/pull/328
https://github.com/dlang-tour/english/pull/316
