Man page for jdb breakpoints incomplete.

In the Breakpoint Commands section of the "jdb" man page it talks
about the "clear" command which is used while running jdb.
The "clear" command allows the user to clear a breakpoint as indicated
in the man page but is also will give a list of breakpoints that
the user has set which is *very* useful.

For example:
main[1] clear
Current breakpoints set:
        sun.tools.agent.Breakpoint:11
        sun.tools.agent.Breakpoint:15

As a user debugging a program this information is very useful and we
should make sure we document this in our man page for jdb.
