 FWIW, the putative 'bug' is documented on the manpage for expr.
 
 There is nothing wrong with the 1003 regex handling.
 
 It is operator/operaand recognition in expr.  Using something that
 is parsable as an operator _as_ an operand. is a syntax error for 
 the ':' operator -- EXPRESSLY so stated on the manpage. 
 Using _any_ token that is parsable as an 'operator' (arithmetic, or
 logical) as an operand for ':' will result in the  same non-bug error
 
 The 'Examples' section of the manpage documents a work-around --
 actually using '/' as the example.
 
 Shoulc be closable -- with the traditional IBMism -- "it's not a bug,
 it's a _feature_, and =documented= as such."    *BIG* grin.
