Improved config_chain parsing by using escape for \ " and ' (close #1952)
It also add checks against failed malloc. The option value should be escaped by \ for the mentionned characters and only for them (and only one time). For example dst="test \"ok\".mp3" will assign the value test "ok".mp3 to the option dst. The following one dst="c:\test\\'bla'bla.txt" will assign the value c:\test\'bla'bla.txt You can use the functions - config_StringEscape (allocates memory) - config_StringUnescape (does not allocate memory).
