UserSettings functions should have the same signature as Config

[kke]

I can't do something like this:

type sshconfig interface {
  GetAll(alias, key string) ([]string, error)
}

var sshConfig sshconfig

func initSshConfig() {
  if path := os.Getenv("SSH_CONFIG"); path != "" {
    f, _ := os.Open(path)
    cfg, _ := ssh_config.Decode(f)
    sshConfig = c
    return
   }
   sshConfig = ssh_config.DefaultUserSettings
}

==>

		have GetAll(alias string, key string) []string
		want GetAll(alias string, key string) ([]string, error)

~~I think I can use GetAllStrict~~ (no, ssh_config.Config does not have GetAllStrict)

Actually, I think what I want to do is overwrite UserSettings.userConfig or UserSettings.configFinder.

The only exposed setting is IgnoreErrors.

Perhaps something like NewUserSettings(params).

edit a year later: i have no clue what i'm talking about in this comment.
