Subject: md5sum, sha*sum: also accept openssl checksum syntax

* src/md5sum.c (split_3): Accept openssl checksum syntax, which
differs only by two spaces from that of the bsd checksum tools:
openssl: MD5(f)= d41d8cd98f00b204e9800998ecf8427e
bsd:     MD5 (f) = d41d8cd98f00b204e9800998ecf8427e

 * Noteworthy changes in release ?.? (????-??-??) [?]
 
+** Bug fixes
+
+** New features
+
+  md5sum --check now also accepts openssl-style checksums.
+  So do sha1sum, sha224sum, sha384sum and sha512sum.
