I wouldn't rule it out but I couldn't think of one offhand.

What is hard about it?

In mi_cmd_break_insert, if '-s' was given, use argv[oind+1] through
argv[argc-1] as the arguments.  Maybe the hard part is getting this
through create_breakpoint?  That is just further proof that it is a bad
API.

TBH I don't see why this needs to be in -break-insert.  A new command
seems cleaner to me.  But I don't want to press too hard either.
