Spell checking: exclude (language-specific) escape sequences from spell checking.

[MisterScott]

For spell checking, exclude (language-specific) escape sequences from spell checking.

For an example in 'C', \nallocated is marked as misspelled, when it is a followed by correctly spelled "allocated".

Escape sequences will vary by language.

Looks like the spell checker is implemented by JDT UI
