[Bug: 21.5-b19] constrain-to-field is undefined (fill-paragraph-or-region fails)

================================================================ Dear Bug Team! paragraphs.el now uses an undefined function constrain-to-field. This breaks several things, including the submission of bug reports and fill-paragraph-or-region. b18 was fine, b19 is broken: # bind (standard-output stack-trace-on-signal debug-on-signal stack-trace-on-error debug-on-error) # (unwind-protect ...) constrain-to-field(nil 218 t) # bind (found-start start sp-parstart parsep parsep parstart fill-prefix-regexp opoint arg) forward-paragraph() # bind (after-line fill-prefix paragraph-ignore-fill-prefix paragraph-separate paragraph-start) # (unwind-protect ...) # (unwind-protect ...) # bind (has-comment has-code-and-comment comment-fill-prefix justify) lisp-fill-paragraph(nil) # bind (function fill-paragraph-function arg) #<compiled-function (arg) "...(54)" [function before end start arg fill-paragraph-function nil forward-paragraph newline 1 backward-paragraph fill-region fill-region-as-paragraph use-hard-newlines] 5 1160481 (list (if current-prefix-arg (quote full)))>(nil) call-interactively(fill-paragraph) # bind (arg) fill-paragraph-or-region(nil) # bind (command-debug-status) call-interactively(fill-paragraph-or-region) # (condition-case ... . error) # (catch top-level ...) To reproduce: xemacs -q and invoke fill-paragraph-or-region on some text. ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: CYGWIN_NT-5.0 paston01 1.5.12(0.116/4/2) 2004-11-10 08:34 i686 unknown unknown Cygwin ./configure '--with-dragndrop' '--debug=no' '--error-checking=none' '--with-x11=no' '--site-includes=/usr/include/noX' '--pdump' XEmacs 21.5-b19 "chives" (+CVS-20050217) configured for `i686-pc-cygwin'.
