bug#68373: 29.1; Bug in MH-E's support for using openssl to generate the checksum

[Marc Baaden]

The bug occurred with MH-E when displaying all new messages with
mh-index-new-messages. This supposedly shows first the folder name, then
it's new messages, then next folder name and so on. In my case all new
messages were shown in a list but folder names were missing. In the end
it turned out the reason was that no X-MHE-Checksum: was created in the
messages.

The machine was freshly re-installed after a crash. It natively has md5
installed, but not md5sum. Openssl was installed. In principle md5
should be invoked as fallback for missing md5sum. This did not happen
and no error was thrown. The supposed reason: checking for openssl
may have led to skip an explicit test for md5sum? There has been an
exchange on the mh-e-users list on this topic and it was concluded a bug
report should be filed.
