Is it?  I couldn't find anything about this in e.g. the coding
standards.

I find -i=mi4,mi3 more intuitive here; I'd interpret -i=mi4 -i=mi3 as
either "use both" or "use the last one on the command line", but
-i=mi4,mi3 as either "use both" or "use the first one which works".
I think the "use the last one" behavior is fairly common; otherwise
there'd be no way to invoke a command specified as "gdb -i=mi2" in mi1
mode without sedding the user-specified command looking for -i options.

Of course I don't have a strong opinion on this.  Just musing; feel
free to ignore.
