Fix the compatibility function sha1 so that it reads from
stdin (and not a file with a zero-length file name) when
no argument is supplied.

Linux as I don't have access to a Mac.

I just ran into this yesterday.  I stupidly changed the caller of sha1 to
pass in - for the filename.  That worked for me since I ended up using the
sha1sum implementations; openssl is not happy about that.  So, your patch
looks good.

Now, I should actually figure out how to get the git repo out there again.

Thanks,

Jeff.

$ openssl dgst -sha1 </dev/null

Was that on a Darwin? If so, my fix obviously needs some
work on that platform. I tested openssl-0.9.8o on Ubuntu
11.04, and here it looks like this:

$ openssl dgst -sha1</dev/null
da39a3ee5e6b4b0d3255bfef95601890afd80709
$ openssl version
OpenSSL 0.9.8o 01 Jun 2010

No.

Here's the output from my Mac (running Snow Leopard):

$ openssl dgst -sha1</dev/null
(stdin)= da39a3ee5e6b4b0d3255bfef95601890afd80709
