The default nanorc should include a commented line to add all extra
syntaxes.

I renamed mutt.nanorc to email.nanorc, because I have an actual
mutt.nanorc to colorize all of the mutt config files.

email.nanorc is used to edit existing emails that do contain headers,
but mostly used to compose new emails which don't. Trying to color
headers would lead to incorrect coloring when composing an email with a
line that begins with a header name followed by a colon. I only color
end of line whitespace, email addresses, urls and three levels of
quotes.

color #F0F:magenta "^>.*"
color #C0C:magenta "^> ?>.*"
color #70C:magenta "^> ?> ?>.*"
color blue "[-.+_a-zA-Z0-9]+@[-.a-zA-Z0-9]+"
color #807FFF:brightblue "(https?|ftp)://[-.,/%~_:?&=#a-zA-Z0-9]+"
color black,blue "[[:space:]]+$"
