[.3,'.2',.1] sorts to [0.1, 0.3, ".2"]

[macronx]

I hope this isn't duplicated elsewhere.

[.3,'.2',.1].sort(naturalSort)

[0.1, 0.3, ".2"]

Seems that the floating point regex requires an integer part, so the '.2' is chunked to ['.', 2] while the non-string numbers are recognized by javascript as numbers and are not chunked.

Changing /\d+(?:.\d_)?/ to /(?:\d+(?:.\d_)?|.\d+)/ resolves this, but I don't know if it breaks other unit tests and haven't used github long enough to feel comfortable contributing to "live" code (and may not have the required tools installed).

original: sign? integer fraction? exponent?
modified: sign? ( integer fraction? | fraction ) exponent? // second fraction requires digits
