util: add getbefloat64 As far as I can tell, this is wrong. double's format isn't strictly specified in the C standard, but the wikipedia article implies that platforms implementing optional Annex F "IEC 60559 floating-point arithmetic" will work correctly. My local C experts believe doing *((double *) &t) is a strict aliasing violation, and that using a union is also one. Doing memcpy appears to be the least-undefined behavior possible.

When Mercurial accepts more than one revision, they may be specified
individually, or provided as a topologically continuous range,
separated by the ":" character.

The syntax of range notation is [BEGIN]:[END], where BEGIN and END are
revision identifiers. Both BEGIN and END are optional. If BEGIN is not
specified, it defaults to revision number 0. If END is not specified,
it defaults to the tip. The range ":" thus means "all revisions".

If BEGIN is greater than END, revisions are treated in reverse order.

A range acts as a closed interval. This means that a range of 3:5
gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
