[Abcde-users] Patch to tidy the main routine, and avert loosing variable declarations by not using subshells

[Roger]

Found two more sections being piped using subshells, and should likely just be 
sectioned using curly braces.

Probably best just to bundle all these into one patch.

Again, this patch just merrily replaces the parenthesis of the piped sections 
and then indents the sectioned code within curly braces for readability.
