regenerate. This change makes printdepends and printindex more
independent, because before this change, printindex could use the
cache provided by printdepends, but not the other way round.
- Fixed the section "Sanity checks, part 2" by allowing newline
characters in the list of packages from which the index is built.
This bug just hasn't been noticed because the list taken from the
cache did not have newlines at all.
The '-' character is not included in the $allowed variable because it
is handled specially and differently by sh(1) and tr(1).
- Updated the printindex man page.
