---------------------------+------------------------------------------------
Followup to #12650. There are a number of tickets open due to the use of
`simplify_radical()` in `simplify_full()`. By adding an `unsafe` argument,
we make sure the user really knows what he's doing.
For example,
{{{
sage: f = sqrt( (x+1)^2 )
sage: f.full_simplify(unsafe=True)
x + 1
}}}
This will fix at least,
* [http://ask.sagemath.org/question/767/simplification-errors-in-simple-
expressions Ask Sage 767]
* #3520 - inconsistency in simplify_radical
* #11668 - `abs(a+b)^2 == (a+b)^2`
* #11934 - Symbolic simplification error
* #12322 - invalid simplification of complex logarithm
And maybe more.
