Trace statement in markdown.cpp

When we run the markdown processor with tracing on Windows we see a.o.
```
class QCString __thiscall Markdown::detab(const class QCString &,int &) data=[    \\page ExamplePag]
```
so some "strange: characters at the end., due to a hard coded ellipse. Expected would be something like:
```
class QCString __thiscall Markdown::detab(const class QCString &,int &) data=[    \\page ExamplePag...]
```
