I tend to agree.  The automatic mirroring is not 100% correct, but
it's probably right 80% of the time, and the rest could be fixed by
introducing a command to mirror the character at point.

Yes, that's exactly one manifestation of why the automatic mirroring
is wrong: it assumes too much about the application which will get
this input.
