Allow a CC Mode derived mode to have strings delimited by single quotes.
Also fix the bug where the delimiters of '\033', etc. got the error face. * lisp/progmodes/cc-langs.el (c-single-quotes-quote-strings): Enhance the docr string. (c-string-delims): Change doc string to doc comment. * listp/progmodes/cc-mode.el (c-before-change-check-unbalanced-strings): In searches and comparisons, take account of the string delimiters possibly being '. Fix argument in call of c-before-change-check-unbalanced-strings. (c-parse-quotes-before-change, c-parse-quotes-after-change): Bind case-fold-search to nil. Analyze escape constructs inside character constants more accurately, in particular accepting as valid more than one character after /[0-7], /x, /u, and /U. Amend calculations to account for this extra length.
