Number-suffixes (".2" in "0.1.2") with a dot are lost when scrubbing a string that contains a number.

[JoachimK]

When scrubbing a string that has a number with more then one decimal dot, the second dot and numbers after that are ignored and NOT preserved while scrubbing/nudging.

E.g. when nudging up "1.2.7" it becomes "1.3". I'd say it should be "1.3.7" instead.

With 1f6584c, the behavior is different:

• Scrubbing the first or second digit changes them as a pair (treating them as a floating point number, which isn't really correct) -- but the suffix is preserved.
• Scrubbing the last digit (previously impossible) repeatedly inserts 0s to the left of it. Definitely wrong.

Ideally it would be smart enough to recognize this as not a proper number, and treat the three segments as independent integer values. I'll try to work on that soon.
