That also impacts the concept of using escapes to opt out,
since the library method cannot see escapes, while the
compiler can see them.

I suggest the following rule:  If the string contains
quoted whitespace (especially \n and \040, maybe
others), then the compiler does *not* call the library
routine to strip leading spaces.  Thus, visibly taking
control of at least one element of whitespace in the
body of the string constitutes an opt-out from
any edits to the remaining whitespace.

Thus, *if* javac hands the string to the library method,
we already know that the library method won't be
meddling with escaped spaces or newlines.
