I like this string_list approach much better, but it's too bad we have
to go through these contortions with the strdup flag to get the memory
ownership right.
If we had a string_list_appendf(), then we could just leave that flag
alone and this:

would become:
msgs[ERROR_WOULD_OVERWRITE] = msgs[ERROR_NOUPTODATE_FILE] =
string_list_appendf(&opts->msgs_to_free, msg, cmd, cmd)->string;
I don't know if that's worth it or not (I suspect that there are other
places where appendf would be handy, but I didn't poke around).
