- add .Os, it is mandatory.
- don't redeclare .Nm when it's not needed.
- fix some warnings (checked with mandoc -Tlint).
- remove some leftover old stuff.
Equivalence classes are a hard matter and there's still no "standard"
way to solve the issue.
Previously, tr would just skip those classes, but it's much
better when it resolves a [=c=] to a normal c instead of treating
it as a literal.
Also, reflect recent changes in the manpage (octal escapes) and fix
the markup in some areas.
- Added support for character ranges ( a-z )
- Added support for complementary charset ( -c ), only in delete mode
- Added support for octal escape sequences
- Unicode now only works when there are no octal escape sequences,
otherwise behavior is not predictable at first sight.
- tr now supports null characters in the input
- Does not yet have support for character classes ( [:upper:] )
*sum tools: -c was added
tr: -d flag was added.
xargs: -n flag was added.
cmp: minor typo (change to lowercase).
