ef1c535727 spec: examples of untyped boolean, string constants 
This is a spec correction, not a language change.
The implementations have behaved like this for years
(and there are tests to that effect), and elsewhere in
the spec true and false are defined to be untyped
boolean constants.

60f564fc37 crypto/dsa: don't truncate input hashes. 
Although FIPS 186-3 says that we should truncate the hashes, at least
one other library (libgcrypt) doesn't. This means that it's impossible
to interoperate with code using gcrypt if we enforce the truncation
inside of crypto/dsa.

This change shouldn't actually affect anything because nearly
everybody pairs DSA with SHA1, which doesn't need to be truncated in
either case.

e4de2e7fd0 math: document special-cases behavior for Dim, Max and Min 
Max returns +Inf if x or y is +Inf; else it returns NaN if either x or y is NaN. Max(-0, -0) returns -0.
Min returns -Inf if x or y is -Inf; else it returns NaN if either x or y is NaN. Min(+0, -0) returns -0.
Dim(+Inf, +Inf) = NaN, Dim(-Inf, -Inf) = NaN and Dim(NaN, anything) = NaN.
Also, change "conditions" to "cases" for Sin (missed it in previous CL).
