* maint: Start preparing for 1.5.1.3 Sanitize @to recipients. git-svn: Ignore usernames in URLs in find_by_url Document --dry-run and envelope-sender for git-send-email. Allow users to optionally specify their envelope sender. Ensure clean addresses are always used with Net::SMTP Validate @recipients before using it for sendmail and Net::SMTP. Perform correct quoting of recipient names. Change the scope of the $cc variable as it is not needed outside of send_message. Debugging cleanup improvements Prefix Dry- to the message status to denote dry-runs. Document --dry-run parameter to send-email. git-svn: Don't rely on $_ after making a function call Fix handle leak in write_tree Actually handle some-low memory conditions Conflicts: RelNotes git-send-email.perl
