Subject: Using spaces in a PREDEFINED setting

When having in the settings:
```
PREDEFINED += "HELP_DOT_SPACE( xs , ys , ... )=enum class xs { ys, __VA_ARGS__}"
```
we expect that the result is similar to when using a PREDEFINED setting:
```
#define LOC_SPACE( xs , ys , ... ) enum class xs { ys, __VA_ARGS__}
```
this is not the case especially due to the space after the last named argument.

We see that when we have:
```
LOC_SPACE(locSpace2, last);
```
we get
```
enum class   locSpace2 { last }
```
and when having:
```
HELP_DOT_SPACE(dotSpace2, last);
```
we get:
```
  HELP_DOT_SPACE (dotSpace2, last)
```
