Leading underscores and dashes not respected.

[thoughtmanifest]

Any string that starts with an underscore or dash has the underscore or dash removed in the result.

ex:
(->kebab-case "_my_string") => "my-string"
(->kebab-case "-my-string") => "my-string"

ex of NullPointerException:
(->kebab-case "-") =throws=> NullPointerException java.lang.NullPointerException
(->kebab-case "_") =throws=> NullPointerException java.lang.NullPointerException

This is also true for any number of dashes or underscores:
(->kebab-case "__----__----") =throws=> NullPointerException java.lang.NullPointerException

Also, empty strings throw the same exception:
(csk/->kebab-case "") =throws=> NullPointerException java.lang.NullPointerException

Since they all send nil to clojure.string/lower-case instead of empty string or leaving the dashes and underscores intact

[qerub]

The exception issue is solved in master.

A workaround for (->kebab-case "-my-string") => "my-string" is to provide an extra :splitter \- argument after I've merged #23.

Let me think a bit about what the default behavior should be…

What would you expect (->kebab-case "-_ f") to return?

[thoughtmanifest]

I suppose my expectation would be for it to honor all instances of the dash and replace all underscores with a dash and any number of consecutive whitespace with a single dash.

"-_ f" => "--f"
"---___   f" => "------f"
"___   f   ---   f" => "---f---f"

This should hold true for keywords as well.
