* lisp/org-table.el (org-table-remote-reference-indirection): Use the
optional arg START of `string-match' to improve performance and to
avoid endless loop on user error.
* doc/org.texi (References): Add description for indirection of
NAME-OR-ID.
* lisp/org-table.el (org-table-eval-formula): Make use of
`org-table-remote-reference-indirection'.
(org-table-remote-reference-indirection): New function.
* testing/lisp/test-org-table.el
(test-org-table/remote-reference-indirect): Change to use remote
reference indirection.
* testing/lisp/test-org-table.el
(test-org-table/remote-reference-indirect): Add a use case of
summarizing two tables with a sum into one table for the total; as a
preparation for remote reference indirection.
* lisp/org.el (org-match-substring-regexp): Simplify syntax when not
using braces. Also make the variable a defconst.
(org-match-substring-with-braces-regexp): Make the variable a defconst
and remove a useless group in regexp.
* lisp/org-element.el (org-element-subscript-parser,
org-element-superscript-parser): Adapt to group changes.
* lisp/org-element.el (org-element--cache-root): New function.
(org-element--cache-sync, org-element-cache-get): Use new function.
This is a workaround for `avl-tree--root' bug before Emacs 24. Thanks
to Daniel Clemente for reporting it.
* lisp/org.el (org-get-previous-line-level): Do not call
`org-current-level' twice unless necessary. Also, avoid using
`line-number-at-pos' when the information needed is to know if point
is in the first line of the visible part of the buffer.
* doc/org.texi (Global and local cycling): Remove "Initial visibility"
and "Catching invisible edits" subsections since they already are
located in "Visibility cycling" menu.
* lisp/ox-html.el (org-html-checkbox-types): Fix docstring.
(org-html-checkbox-type): Use symbols instead of strings. It avoids
to rely on `intern' later on. Modify docstring so its first line
contains only a complete sentence.
(org-html-checkbox): Use `assq' instead of `assoc'.
This fixes 2c782da801.
(org-html-checkbox-types): New constant. Contains unicode, ascii and html
checkbox alists.
(org_html_checkbox_type): New customzation variable can be set to one
of the above choices. Defaults to "ascii"
(org-html-checkbox): Use the appropriate set of checkboxes as
specified in `org-html-checkbox-type'.
