Hi Stefan,

It doesn't do the same, but it's not my code, so...

AFAIR the difference is in how shell does the expansion, where "$@" can break 
single arguments in to garbage because of white spacing and the 
COMMAND="$COMMAND \"$arg\"" re-adds quotes properly to not break single 
arguments that have white space.  (Or less likely it was an sg issue of passed 
in arguments?)

The full explanation is (was) buried on that thread somewhere, or on something 
that thread links(ed) to.  It made sense to do at the time, but I'd need 
someone else with a much better depth of skill with bash/shell/sg to 
authoritatively explain it.

Best,
Michael
