[!!!][BUGFIX] Avoid to call stdWrap twice

Using the recursive stdWrap will work on the stdWrap twice, although the
output is created only once.

Fix this by preventing the recursive call to stdWrap() if the
current function name is "stdWrap" as this will trigger a call to
stdWrap_stdWrap() later on anyway.

This will change rendering if LOAD_REGISTER or something similar
is used in a recursive stdWrap context.
