Hello all,
Since there is only one user of sha1's BINARY arg namely canlock-sha1 in
the source tree, I wonder if it is worthwhile to make md5 and sha1 have
similar signature:
(md5 OBJECT &optional START END CODING-SYSTEM NOERROR BINARY)
(sha1 OBJECT &optional START END CODING-SYSTEM NOERROR BINARY)
What do you think?

I don't think it's worth the trouble.

Where's the big trouble, if there's only one user right now?
At least, all the command line tools `md5sum', `sha1sum', `sha224sum',
`sha256sum', `sha384sum', and `sha512sum' have the exact same options
and meanings. So I don't see a valid reason to have different lisp
signatures, especially if there's a chance that other algorithms might
be added in the future.
Bye,
Tassilo

Discussing it.
Handling the coding-system parameter.
Writing the patch.
Testing it.
Installing it.
Taking the risk that there are other users out there.
...
