func EditRetryLoop

func EditRetryLoop(prefix string, selectFn func() io.Reader, applyFn func(b []byte) error) error

EditRetryLoop seeds a temp file, prefixed with |prefix|, with content from selectFn and passes it to applyFn. If applyFn errors, the editor will be re-opened with recent error message included in the header comments. The current implementation prefixes comment lines with "#".
