That would be great.

OK, I didn't think that many places in the code would be affected, I'll have to look at the diffs.

I tested it against -jumbo, I was just blind to the case of argc < 2. Running john without either giving it a file or doing ---test or --restore didn't seem very useful. My test linux builds didn't include -jumbo because I don't have OpenSSL loaded on that installation.

I was thinking about the case-senstive/case-insensitive issue with the OpenVMS format and considered modifying the semantics of the FMT_LOADER() function so the return value points to a list (i.e. chain of fmt_main structs) rather than just a single fmt_main struct (the provider of the DLL has to guarantee member next is initialized). Register_dlls() would have to disassemble the list is a way that it could then safely feed each block to register_one() for placement on the global list.
How does john deal with input files with different lines that need to be processed by different formats?
