"""
Gets the input string that was used to set data_source[key] in the data_source specified by where / target_type / target_desc.
Note about data_source behaviour:
If data_source supports input_lookup, but key is not present, this returns default (empty string unless specified).
If data_source does not support input_lookup, we return either None or some information string.
We do NOT raise an exception.
See also get_input_source for a version that determines data_source from the key.
