Recognizing alternative reply prefixes

[Jaron Kent-Dobias]

Hello,

I am frequently exchanging emails with Italians, whose mail clients 
often use the format 'R: [Subject]' in replies instead of 'Re: 
[Subject]'.  Mutt in my locale does not recognize the leading 'R:' as a 
reply prefix and proposes the subject line 'Re: R: [Subject]'.

Can mutt be configured to recognize other reply prefixes automatically?

Cheers,
Jaron
