[Typo3] [loginUser = *] test for BE users?

[Matthew Manderson]

Thanks Martin,

The var 'beUserLogin' seems to be ideal, after you provided this trigger I was 
able to find other examples that show this works easy every time.

However I had trouble as it seems not to want to work in my clean 3.8.0 
install so I tried it in 3.7.0 and it worked perfectly.

If I could just get a login into bugs.typo3.org I could see if this 'feature' 
has already come up....;-)

Thanks, enjoy the day.
Matthew
