man: wording and grammar updates

This is a recurring submission and includes corrections to various
issue spotted. I guess I can just skip over reporting ubiquitous
comma placement fixes…

Highligts in this particular commit:
- the "unsigned" type qualifier is completed to form a full type
  "unsigned int"
- alphabetic -> lexicographic (that way we automatically define how
  numbers get sorted)
