This is the same file I sent:
sh> sha1sum pgbench-continuation-4.patch pgbench-continuation-3.patch 97fe805a89707565210699694467f9256ca02dab
pgbench-continuation-4.patch97fe805a89707565210699694467f9256ca02dab pgbench-continuation-3.patch
The difference is that your version is mime-typed with a generic
Application/OCTET-STREAM
While the one I sent was mime-typed as
text/x-diff
as defined by the system in /etc/mime.types on my xenial laptop.
My guess is that with the later your mail client changes the file when
saving it, because it sees "text".
