[exim] ${local_part:<string>} not unquoting

Hello,

if one accesses the $local_part variable, the result is maybe
lower cased but unquoted if quoting was necessary/used in the
address. Therefor it is necessary to use ${quote_local_part:...}
if a new address is to be constructed from $local_part.

${local_part:<string>} is _not_ removing quoting.

" ${local_part:<string>}

    The string is interpreted as an RFC 2822 address and the local part is
    extracted from it. If the string does not parse successfully, the result is
    empty.
" does not mention quoting, but as an "RFC 2822 address" may include
quoting, I would expect it to be removed here if neccessary, especially as
there is no unquote operator.

Shall I enter a bug report?

Lutz
