Bash Version: 2.05b
Patch Level: 0
Release Status: release

Description:
        When bash is called as "rbash", it should switch to unrestricted
        mode while reading the startup files.  However, this doesn't 
        happen due to the variable 'shell_name' in set_shell_name()
        getting reinitialized to argv0 *after* it is stripped from any
        preceding '-' character, causing the shell_is_restricted()
        function to fail since it looks for "rbash", not "-rbash". This in
        turn causes the switching to unrestricted mode during parsing of
        the startup files to not happen.

Repeat-By:
        Invoking bash as "rbash".
