about internal exported symbols

[Stanislav Ievlev]

Greetings!

I have a question about ncurses shared library exported symbols.
Why this library exports a lot of internal functions with _nc prefix?
Why ncurses tests use these internal functions, e.g. _nc_free_and_exit() via 
ExitProgram() macros?

I think it's bad:
First, it's unfair to use internal symbols in the example programs.
Since initscr() generates permanent memory leak by design,
it may be better to recommend newterm/delscreen?
Second, these usually unused global symbols enlarge symbol lookup table
and make program startup slower.
