Log Message:

Backport to 8.4 (Don Porter's work).

When no requirements are supplied to a [package require $pkg] and
[package unknown] is invoked to find a satisfying package, pass the
requirement argument "0-" (which means all versions are
acceptable). This permits a registered [package unknown] command to
call [package vsatisfies $testVersion {*}$args] without any special
handling of the empty $args case. This fixes/avoids a bug in
[::tcl::tm::UnknownHandler] that was causing old TM versions to be
provided in preference to newer TM versions.  Thanks to Julian Noble
for discovering the issue.
