<     Windows does not support returning values from script.
<     Therefore temporary files may be used to keep some information like commit message
<     If the 'message' starts with 'file:', and the file with indicated name exists, then read the text message from the file rather then using the text directly
<     Even though actual message also may start with such prefix, it is very unlikely that the file exists with such a name by accident
