Re: Patch: Syntax and Hard Newlines

...  yet there is method in 't.  I nearly spent an hour analyzing
longlines-mode and writing my proposal.  Please spend a few minutes on
the following questions:

- longlines-mode substitutes newlines for spaces.  This means that any
  function based on scan_newline (like `goto-line') may get me results
  that are inconsistent with those of tools analyzing the file my buffer
  visits.  How can I treat compiler or grep output with longlines-mode?

- Matching against the regexp "." may get me different results for the
  same buffer with longlines-mode disabled and enabled.  Ignore that?

- longlines-mode may wrap a regexp like "[ \t]*" at the space character.
  How can I evaluate a wrapped regexp like that?

- How can I avoid that longlines-mode wraps a Lisp or Perl expression at
  a space preceding a left paren (with the left paren ending up at bol
  and messing up `beginning-of-defun-raw' and thus font-locking)?

- How can I avoid that longlines-mode wraps a C string and
  `c-font-lock-invalid-string' complains?

- I put an arbitrary text property on a space character.  longlines-mode
  wraps the line at that character.  How can I restore that property
  when turning off longlines-mode?

- I use two windows of different widths to simultaneously show one and
  the same buffer.  How can I adapt longlines-mode to wrap at the right
  borders of my windows?
