Summary
=========

Doxygen fails to parse default values with backslashes, like

     string someFunc(const string& splitOn = " \n");

(it seems any backslash inside default value suffices, I saw it on "\t\r\n", "\n" and some similar)

The problem appears in 1.8.13 but was not present in 1.8.11

Detailed example
======================


// doxygen 1.18.13 fails to parse parameters with default values containing backslash.
// In older versions they worked correctly.
//
// To test:
//     doxygen -g test
//     doxygen test
//
// Problems:
//
// - the following warnings are reported:
//
//     problem.hxx:31: warning: argument 'value' of command @param is not found in the argument list of ThisFails()
//     problem.hxx:37: warning: argument 'value' of command @param is not found in the argument list of ThisFailsToo(const string &arg1)
//     problem.hxx:37: warning: argument 'arg2' of command @param is not found in the argument list of ThisFailsToo(const string &arg1)
//
// - in generated docs, doxygen claims the following signatures:
//
//    string ThisFails ( )
//
//    string ThisFailsToo ( const string &      arg1)
