Greetings;
When I run anything that is actually a shell script starting with 
#!/bin/sh and maybe any thing that uses a shell function I get five or 
six screens full of messages that look like the following and all start 
with /bin/sh
    /bin/sh: _openssl: line 25: syntax error near
        `unexpected token `('
    /bin/sh: _openssl: line 25: ` -@(in|out|oid))'
    /bin/sh: error importing function definition for
        `_openssl'
    /bin/sh: _service: line 4: syntax error in
        conditional expression: unexpected token `('
    /bin/sh: _service: line 4: syntax error near `@(*'
    /bin/sh: _service: line 4: ` [[ ${COMP_WORDS[0]} !=      
@(*init.d/!(functions|~)|service) ]] && return 0;'
One example is  /usr/bin/bashbug
but all scripts that start with  #!/bin/sh
seem to have the problem.
One function that has the problem is one I wrote that does an ls and 
pipes it to less. As follows;
    function lm ()
        {
            ls -laNF "$@" | $(which less)
            }
Anybody have any idea about what is causing these errors
or where to look?
