Bug #118289 for MIME-tools: MIME::Words::encode_mimewords includes spaces in the encoded word

Dear maintainer, this small program: $ cat mimewords.pl use utf8; use 5.022; use warnings; use MIME::Words qw(encode_mimewords); say encode_mimewords('Moritz Bößl <foo@example.com>'); produces as output: $ perl noris/mimewords.pl Moritz =?ISO-8859-1?Q?B=F6=DFl=20?=<foo@example.com> The space between the second word and the less-than sign has been encoded. The expected output is: Moritz =?iso-8859-1?Q?B=F6=DFl?= <foo@example.com> RFC2047 says: (3) As a replacement for a 'word' entity within a 'phrase', for example, one that precedes an address in a From, To, or Cc header. The ABNF definition for 'phrase' from RFC 822 thus becomes: phrase = 1*( encoded-word / word ) In this case the set of characters that may be used in a "Q"-encoded 'encoded-word' is restricted to: <upper and lower case ASCII letters, decimal digits, "!", "*", "+", "-", "/", "=", and "_" (underscore, ASCII 95.)>. An 'encoded-word' that appears within a 'phrase' MUST be separated from any adjacent 'word', 'text' or 'special' by 'linear-white-space'. In the output, the encoded word isn't separated from the "special" less-than sign by a linear-white-space. I've tested this with version 5.508 of MIME-tools. Best regards, Moritz Lenz
