The overall change is to add cell renaming, that is setting fancy names for cell symbols other than name matching "\\`[A-Z]+[0-9]+\\'" regexp . (ses-create-cell-variable): New defun. (ses-relocate-formula): Relocate formulas only for cells the symbols of which are not renamed, i.e. symbols whose names do not match regexp "\\`[A-Z]+[0-9]+\\'". (ses-relocate-all): Relocate values only for cells the symbols of which are not renamed. (ses-load): Create cells variables as the (ses-cell ...) are read, in order to check row col consistency with cell symbol name only for cells that are not renamed. (ses-replace-name-in-formula): New defun. (ses-rename-cell): New defun. (ses-call-printer-return, ses-cell-property-get) (ses-sym-rowcol, ses-printer-validate, ses-formula-record) (ses-create-cell-variable, ses-reset-header-string) (ses-cell-set-formula, ses-repair-cell-reference-all) (ses-self-reference-early-detection, ses-in-print-area, ses-set-curcell) (ses-check-curcell, ses-call-printer, ses-adjust-print-width) (ses-print-cell-new-width, ses-formula-references, ses-relocate-formula) (ses-aset-with-undo, ses-load, ses-truncate-cell) (ses-read-column-printer, ses-read-default-printer, ses-insert-row) (ses-delete-row, ses-delete-column, ses-append-row-jump-first-column) (ses-kill-override, ses-yank-pop, ses-yank-cells, ses-yank-tsf) (ses-yank-resize, ses-export-tab, ses-mark-row, ses-mark-column) (ses-renarrow-buffer, ses-insert-range, ses-insert-ses-range) (ses-safe-printer, ses-safe-formula, ses-warn-unsafe, ses--clean-!)
