Fixed. The new "unssh" tool takes a list of filenames (as arguments)
and writes its output to stdout.

Auto-detection added.

A silly bug (missing newline handling) in my code broke "--show". Fixed.

I have tried to address these issues in the new version of the patch
(attached as well as uploaded to the wiki).
Usage:
1. Run unssh on private key file(s) as "unssh [key file(s)]". Output
is written to standard output.
2. Run JtR on the output generated by unssh as "john [output file]".
...
For a while, I am switching to "adding support for FileVault and
archive files cracking" activity. Will revisit this patch later.
