One more fix to headings pushed...

I haven't found any guidance on how to treat abbr. in headers but usually it says do not use it. If we're using them how should the abbr. be written NFD or Nfd ?

I think that's prolly a good advise 😄

As I speculated above, if NFD would be used as a stand-alone abbreviation I'd keep it NFD. However as part of the name of the executable I'd prolly use Nfd

Changed headings

• NFD-Master Commandline Flags -> Command line flags of nfd-master
• NFD-Worker Commandline Flags -> Command line flags of nfd-worker
• NFD-Worker Configuration File Reference -> Configuration reference of nfd-worker
• End-to-End Test Configuration File Reference-> Configuration file reference of end-to-end tests

Ok enough lamenting, only one nitpick and I would say looking good.
