I think using commas systematically is making it worse for ourselves,
since it prevents us from using gdb_buildargv to parse the command
arguments for us. Commas also have a meaning in C, so arguably
they could be used in expressions as well. But, if that's the way
people prefer, then having a standard gdb_buildargv-like API that
everyone consistently uses will make it easier for me to accept
that decision.
