 * if they exist at the _end_ of a property decl line (i.e. as part
 * of a _value_), they are preserved, as outlined in the Java API:
 *
 * "Any whitespace after the key is skipped; if the first non-
 * whitespace character after the key is = or :, then it is ignored
 * and any whitespace characters after it are also skipped. All
 * remaining characters on the line become part of the associated
 * element string."
 *
 * @param iStr An input stream from which the new properties are to be
 *  loaded (should already be initialized).
 * @param prop A set of properties to which the properties from

 *  removed from all values), will be returned via the parameter.
