The "A" packet was added in 1999 as a "reserved" packet,

+@item set program arguments @strong{(reserved)} @emph{(optional)}
+@tab @code{A}@var{arglen}@code{,}@var{argnum}@code{,}@var{arg}@code{,...}

but the "reserved" marker is removed in
b8ff78cefa335846b4303f303847a4d69e652795 (2005),

- Remove "(reserved)" markers on 'A' and 'I' packets; it's unclear
what this ever meant.

Nowadays, we still can't pass arguments in remote debugging. If "A" still
meets our needs, we can use it in the future to pass arguments.
