I set to C, to ensure that the output is not localised from the other  
end. But that wouldn't work in different locales if you wanted to  
capture 3rd party error messages in other languages. So it probably  
should be a plugin writer's decision whether to set LC_ALL=C.

As to the whole environment, I can't recall why it is wiped. I can see  
that PATH could have been altered which maybe a security risk, but  
that seems like a bad excuse, especially if your system requires  
different PATHs to be set to get to some binaries (*cough*, Solaris).
