[O] [PATCH] org-table.el: Fix regexp used for splitting data rows when computing a formula

[Piotr Gajewski]

* lisp/org-table.el (org-table-eval-formula): Fix regexp
  used for splitting data rows.

* Explanation /root node/

*** Example 1: Spaces ' ' in front of a data row (OK)

    |---+-----+------+---+----+-----|
    | ! | sum |      | a |  b |   c |
    |---+-----+------+---+----+-----|
    | # | 111 | 1000 | 1 | 10 | 100 |
    |---+-----+------+---+----+-----|
    #+TBLFM: $2=$a+$b+$c

    List of values after splitting data row:
    ("#" "" "1000" "1" "10" "100")

    Formula is computed correctly.

*** Example 2: Tabulators '\t' in front of a data row (ERROR)

    |---+------+------+---+----+-----|
    | ! |  sum |      | a |  b |   c |
    |---+------+------+---+----+-----|
    | # | 1011 | 1000 | 1 | 10 | 100 |
    |---+------+------+---+----+-----|
    #+TBLFM: $2=$a+$b+$c

    List of values after splitting data row:
    ("\t" "#" "" "1000" "1" "10" "100")

    There is an extra field containing '\t' character(s).
    All /genuine/ values are shifted to the right.
    Consequently, references to fields lookup the wrong values.
