#6030: formula error in log1p docs
---------------------------------------------------+------------------------

The documentation page for log1p mentions the alternative formula:
log(1+x) == (log(1+x) * x) / ((1-x) - 1)
This is apparently wrong. The correct formula is:
log(1+x) == (log(1+x) * x) / ((1+x) - 1)
(Note the sign of x in the denominator.)
