-  "Proof-assistant specific function for parsing characters for
-  indentation which is invoked in `proof-parse-to-point.'. Must be a
-  function taking two arguments, a character (the current character)
-  and a stack reflecting indentation, and must return a stack. The
-  stack is a list of the form (c . p) where `c' is a character
-  representing the type of indentation and `p' records the column for
-  indentation. The generic `proof-parse-to-point.' function supports
-  parentheses and commands. It represents these with the characters
-  `?\(', `?\[' and `proof-terminal-char'. ")

-;; This is quite different from sml-mode, but borrows some bits of

-;; parse-to-point: If from is nil, parsing starts from either
-;; proof-locked-end if we're in the proof-script-buffer or the
-;; beginning of the buffer. Otherwise state must contain a valid
