Code reproducing the issue

No response

Expected Behavior

Viper should only look at files ending with the config type set, if it has been set. Viper's README reads:

viper.SetConfigType("yaml") // REQUIRED if the config file does not have the extension in the name

I'd expect this to limit the search to only *.yaml files.

Actual Behavior

Viper checks all different kinds of files, also the one without no extension. This is usually the application's binary which obviously isn't a parsable configuration file.

Steps To Reproduce

Add . to the config path
Set the config type to whatever you want (just not an empty string, for example "yaml")
Set the config name to the same as your binary (for example "myapp")
Compile your application (so it's called, for example ./myapp) and run it
