Comment(by robert.marik):
I also think that it is better to keep the function logcontract separately
from simplify_full() since sometimes the contraction of logarithms is not
what user wants. Consider please also option which allows to set
logconfcoef as described in
[http://maxima.sourceforge.net/docs/manual/en/maxima_14.html#Item_003a-
logconcoeffp Maxima]. This allows to contract expressions like
log(x)+1/2*log(8) into log(x*sqrt(8)).
