Doxygen multi-whitespace parsing regression

[alexandruavadanii]

Type: Bug

Before v1.19.4 (up to and including v1.19.3 sorry, I mixed up the versions, apparently it was already broken in v1.19.x, but it works fine in v1.18.5), both Doxygen comments for these 2 functions were parsed correctly:

/**
 * @fn cpptools_test1
 * @brief desc for this void func
 * 
 * @param p1   some pointer
 * @param p2   some other pointer
 */
static void
cpptools_test1(void *p1, void *p2)
{
   (void)p1;
   (void)p2;
}

/**
 * @fn cpptools_test2
 * @brief      desc for this void func
 * 
 * @param  p1  some pointer
 * @param  p2  some other pointer
 */
static void
cpptools_test2(void *p1, void *p2)
{
   (void)p1;
   (void)p2;
}

Starting with v1.19.4, the comment for cpptools_test1 is parsed correctly, but cpptools_test2 (which has 2 or more spaces after the Doxygen keywords) is broken - note the coalescing of the parameter name with its description, as well as keyword highlighting in the function description. Looks like the fn keyword works with 1...4 spaces, but not more.
