lume.wordwrap adds leading newline when first line is longer than limit

[idbrii]

When the input to wordwrap starts with a word longer than the limit, it inserts a leading newline, but it doesn't make sense to add newline there.

Repro

print("|".. lume.wordwrap("supercalifragilisticexpialidocious", 20) .."|")
-- expected:
|supercalifragilisticexpialidocious|

-- actual:
|
supercalifragilisticexpialidocious|
