enc_stat[], hu_stat[]

The definition of enc_stat[] got changed by a pull request nearly a
year ago ('const char *enc_stat[]' -> 'const char *const enc_stat[]')
but the separate declarations for it weren't changed to match.

Make the same change for hu_stat[].  Not sure why the pull request
didn't include it since the old declaration and the usage are same.

The curses one is in code that isn't used.
