Motion and Syntax
=================

   This section describes functions for moving across characters that
have certain syntax classes.

 - Function: skip-syntax-forward syntaxes &optional limit
     This function moves point forward across characters having syntax
     classes mentioned in SYNTAXES.  It stops when it encounters the
     end of the buffer, or position LIMIT (if specified), or a
     character it is not supposed to skip.

     If SYNTAXES starts with `^', then the function skips characters
     whose syntax is _not_ in SYNTAXES.

     The return value is the distance traveled, which is a nonnegative
     integer.

 - Function: skip-syntax-backward syntaxes &optional limit
     This function moves point backward across characters whose syntax
     classes are mentioned in SYNTAXES.  It stops when it encounters
     the beginning of the buffer, or position LIMIT (if specified), or
     a character it is not supposed to skip.

     If SYNTAXES starts with `^', then the function skips characters
     whose syntax is _not_ in SYNTAXES.

     The return value indicates the distance traveled.  It is an
     integer that is zero or less.

 - Function: backward-prefix-chars
     This function moves point backward over any number of characters
     with expression prefix syntax.  This includes both characters in
     the expression prefix syntax class, and characters with the `p'
     flag.
