Given two revision numbers, this figures out which one is greater than the other by stepping along the decimal points until a difference is found, at which point a sign comparison of the two is returned.
Return the logical revision before this one. Normally, this will be the revision minus one, but in the case of a new branch, we strip off the last two decimal places to return the original branch point.
The size of a revision number is the number of portions it has.
For example, 1,2.3.4 is of size 4.
Given a revision number, remove a given number of portions from it. For example, if we remove 2 portions of 1.2.3.4, we are left with 1.2.
Validation function to ensure that a revision number is of the right form.
