stty doc 'enhancements'

[jidanni]

On (info "(coreutils)stty invocation")
say what you mean by Input Settings and Output Settings.
I.e., what you type into the terminal and then goes into... what is
sent from the computer to your terminal...??

After
     `iuclc'
     Translate uppercase characters to lowercase.  Non-POSIX.  May be
     negated.
mention there is no corresponding item to Translate lowercase
characters to uppercase.

Same with lcase, say "ucase" is missing.

Same at
     `olcuc'
     Translate lowercase characters to uppercase.  Non-POSIX.  May be
     negated.
mention there is no 'ouclc' currently.

(They all might be needed when trying to emulate some early computer
system or something one day.)
