I mostly agree for the SoB, but why should a Cc tag have only one email?
The "multiple emails per Cc: field" has been there for a while already
(b1c8a11c8024 released in 2.6.0, sept 2015), some users may have got
used to it. What you are proposing breaks their flow.

I'd find it rather ironic to fix your case by breaking a feature that
has been working for more than a year :-(. What would you answer to a
contributor comming one year from now and proposing to revert your
reversion because it breaks his flow?
All that said, I think another fix would be both satisfactory for
everyone and rather simple:
1) Stop calling Mail::Address even if available. It used to make sense
to do that when our in-house parser was really poor, but we now have
something essentially as good as Mail::Address. We test our parser
against Mail::Address and we do have a few known differences (see
t9000), but they are really corner-cases and shouldn't matter.
A good consequence of this is that we stop depending on the way Perl
is installed to parse emails. Regardless of the current issue, I
think it is a good thing.
2) Modify our in-house parser to discard garbage after the >. The patch
should look like (untested):
--- a/perl/Git.pm
+++ b/perl/Git.pm
@@ -903,11 +903,11 @@ sub parse_mailboxes {
my (@addr_list, @phrase, @address, @comment, @buffer) = ();
foreach my $token (@tokens) {
if ($token =~ /^[,;]$/) {
- # if buffer still contains undeterminated strings
- # append it at the end of @address or @phrase
- if ($end_of_addr_seen) {
- push @phrase, @buffer;
- } else {
+ # if buffer still contains undeterminated
+ # strings append it at the end of @address,
+ # unless we already saw the closing >, in
+ # which case we discard it.
+ if (!$end_of_addr_seen) {
push @address, @buffer;
}
What do you think?
