Escape sequences treated as regular characters

[lmorg]

misspell isn't validating escape sequences and sometimes treating them as misspellings. eg

"iterated element passed\nto it."

Would return

warning: "nto" is a misspelling of "not" (misspell)

where "nto" is actually "\nto" (ie byte(13) + "to" rather than byte(110) + "to")

One year later and misspell still doesn't handle a typical use case correctly. With lots of such false positives it quickly looses its quality.
