Comments from key files not properly respected - breaks based on file name

[numericOverflow]

I have a new edge case for #369. That commit mostly solved the comment workaround but...

If you attach public & private key but don't follow the "standard" naming convention, the public key isn't matched and therefore won't lookup the comment.

Works:

• id_repro1 & id_repro1.pub

Doesn't work:

• id_repro1.key & id_repro1.pub

• filename.xxx & filename.pub

• filename.anything & filename.pub

Steps to reproduce:

Use the keypairs same files from the zip file attached to that issue

• Rename id_repro1 to id_repro1.key (or anything other than the bare, extension-less, typical name for a private key file)

  • 

• attach the id_repro1.key

• attach the id_repro1.pub

  • 

• allow keyagent to use the entry

• Manage keyfiles, pick the id_repro1.key

  • 

• Comment does not appear.
