Use the two names consistentlydocs/guidelines-layout

Progmasoft C/C++ Styles names the repository, where a text speaks of
all of it: the README introduction, the license texts, CONTRIBUTING and
the changelog. Progmasoft Core C++ Coding Guidelines names its C++
guide, and its own documents call it "the guidelines", in the plural
like its name, instead of "the guide" or "this guide"; the verbs follow.
Dated changelog entries keep their wording. Paragraphs that grew past
120 columns are rewrapped; every link and anchor still resolves.

 Code written for C++17 is promised to later standards too, so its checks have to reach them:
