Description

The escape sequence handling in PropertiesConfiguration is different from java.util.Properties.

The Javadoc (of java.util.Properties) basically states that if an escape sequence (backslash + character) is not understood, the backslash is simply removed. PropertiesConfiguration keeps the backslash. E.g. "\ " (backslash + space) should result in just a space. This sequence is used by Properties to escape the first leading space in a property value when writing to a properties-file. PropertiesConfiguration does not understand this syntax. Also (which is technically a different issue but pretty close to this one) does not preserve leading spaces in property values when saving. One could use \u0020 to encode the first leading space, but it would be nicer if it could just use the simpler "\ ".
