String equality isn't consistent

My apologies if this is covered elsewhere. This is v.0065.
The following code
void setup() {
String lines[]={"test"}, B;
B=lines[0];
if (B=="test") {
println("B=='test'");
} else {
println("B!='test'");
}
}
reports that B=='test', as expected. This code
void setup() {
String lines[]=loadStrings("list.txt"), B;
B=lines[0];
if (B=="test") {
println("B=='test'");
} else {
println("B!='test'");
}
}
reports that B!='test'. Of course, using
if (B.equals("test")) {
works fine, but isn't intuitive to a non-Java programmer, and isn't documented.

ah, right..
not really a bug (i'll move to the syntax section), but i'll make a note to try and figure out how to get this in the docs, since we don't spend much time talking about issues like this that we're leaving to java. especially in the case of strings, where comparisons are likely to cause some confusion for newer programmers.
