Reviewed by Gustavo Noronha Silva.

Source/WebCore:

The 'checkSpellingOfString' method assumes that the given string is concatenation of words.
To properly handle spellchecking of each word we need to iterate over the all available
dictionaries ('dictIter').

To allow spellchecking for multiple words, 'dictIter' should be initialized at the beginning
of vector while spellchecking of the word. This ensures performing of spelling for word based on
at least one dictionary.

* platform/text/enchant/TextCheckerEnchant.cpp:
(TextCheckerEnchant::checkSpellingOfString): Moved initialization of 'dictIter' to an inner loop.

LayoutTests:

'checkSpellingOfString' from the TextCheckerEnchant class can not mark multiplie words that are misspelled.
It's possible to mark misspeled string only by defining its location and length.

* platform/gtk/TestExpectations: Added spelling-backspace-between-lines.html to TestExpectations.
