Documentation: `forms-forms-scroll' and `forms-forms-jump' now default to nil. `forms-new-record-filter' and `forms-modified-record-filter' cannot be redefined as functions. Commands and keymaps are changed. Add function key defs. (forms-version): Docstring includes full RCS id. (forms-forms-scroll): Defaults to nil. (forms-forms-jump): Defaults to nil. (forms-mode-edit-map, forms-mode-ro-map): Additional keymaps for edit mode and read-only mode. (forms--new-record-filter, forms--modified-record-filter): Deleted. (forms-mode): Docstring now includes the key bindings, since both edit mode and read-only mode must be supported. Changed `forms-new-record-filter' and `forms-modified-record-filter' semantics: the variable must point to a function and may not be defined as a function anymore. Use three keymaps: `forms-mode-map' (C-c commands), `forms-mode-edit-map' (normal mode) and `forms-mode-ro-map' (read-only mode). The maps are not buffer local. Changed the text of error messages to be more descriptive, and onsistent with the documentation. Moved setting up write-file-hooks and revert-buffer-function to function `forms--change-commands'. (forms--process-format-list): Changed error messages to be more descriptive. (forms--set-keymaps): Setup the three keymaps. (forms--mode-commands): Use new command key bindings. (forms--mode-commands1): New helper function for `forms--mode-commands'. (forms--change-commands): Handle setup of local-write-file-hooks and revert-buffer-function. (forms--help): Show new command bindings. (forms--show-record): Replaced `forms--modified-record-filter' by `forms-modified-record-filter'. (forms-jump-record): Changed error message. (forms-toggle-read-only): New function, replaces `forms-view-mode' and `forms-edit-mode'. (forms-view-mode, forms-edit-mode): Deleted. (forms-insert-record): Replaced `forms--new-record-filter' by `forms-new-record-filter'. (forms-insert-record, forms-delete-record): Disallow in read-only mode. (forms-prev-field): New function.
