* org.el (org-get-refile-targets, org-refile-get-location): Use expanded file name to improve comparison. 2008-12-20 Carsten Dominik <carsten.dominik@gmail.com> * org.el (org-scan-tags): Rescan for tags, to get the correct upcase/downcase stuff. This slows things down for now, but it works. (org-mode): Make sure the tag-faces regexp is initialized. * org-export-latex.el (org-export-latex-links): Fix bug with undefined label. * org-table.el (org-table-get-specials): Set `org-table-current-last-data-line'. (org-table-current-last-data-line): New variable. (org-table-insert-column, org-table-delete-column) (org-table-move-column, org-table-fix-formulas): Call `org-table-fix-formulas' a second time to fix the $LR references. (org-table-get-specials): Add the $LR references to the tables. (org-table-get-formula): Do not offer last-row names as LHS of formulas. * org.el (org-store-link): Capture link description from `org-id-store-link'. * org-exp.el (org-export-html-format-image): Add the / to the end of the <img> tag. (org-export-format-source-code): Surround example by empty lines, to make sure it will not be inside a paragraph. * org.el (org-ido-switchb): New function. 2008-12-20 Carsten Dominik <carsten.dominik@gmail.com> * org-agenda.el (org-agenda-show): New prefix argument FULL-ENTRY. * org.el (org-sort-entries-or-items): Add a COMPARE-FUNC argument.
