isSpaceOrTab()

[Harri Porten]

Hi!

I see that JavaScriptCore is using a helper function isSpaceOrTab() rather
than standard isspace() when parsing date strings. What was the reason?
Speed?

Or was there some confusion because of the function name? Note that
isspace() knows about all the character commonly subsumed under the
category "white space". The following works in Konq and Mozille and will
probably fail in Safari:

  document.write(new Date('\n21\rFeb\f\v\t 2004'));
