History
Mark Johnston afd95785c0 newlocale(3): Fix a memory leak. 
newlocale() optionally takes a "base" locale, from which components not
specified in the mask are inherited.  POSIX says that newlocale() may
modify "base" and return it, or free "base" and return a newly allocated
locale.  We were not doing either, so applications which use newlocale()
to modify an existing base locale end up leaking memory on FreeBSD.

This diff fixes the leak by releasing a reference to the base locale
before returning.  This is less efficient than modifying "base"
directly, but is simpler for an initial bug fix.  Also, update the man
page to clarify behaviour with respect to "base".
