Well, you guys are the experts. I was trying to be "smart" - thinking that
lbracket 'required' the closing right bracket to keep the shell syntax

FYI - It seems to be working as expected, rather designed - so I shall make
some specialized 'buildaix' components to get around the filenameing
problem.

Will keep you posted.
