This PR addresses various typos, missing commas, consistent sentence framing in Doc/library/curses.ascii.rst.
It fixes the following:

• Add Commas in sentences which miss them
• Fix name constants to named constants
• Maintain compound adjectives across the file (replace uppercase letter to upper-case letter ),Since words like lower-case and white- space already follow it.
• In functions such as isprint(), ispunct() , isgraph() ,the sentences were made consistent with any printable ASCII character.
