[PATCH] Change C-' behaviour on #+TBLFM: line

[Torsten Wagner <torsten.wagner@gmail.com>]

Hi,

Short description:

I recently started to use tables in org-mode. Having the pointer inside
the the table and pressing C-c' I can enter the formula buffer.
However, placing the pointer on the #+TBLFM: line C-c' results in "Find
file or URL:".

If even more people believe this is confusing, I would suggest to switch
the behaviour. C-c' on a #+TBLFM: line should open up the formular buffer.

Longer Explanation:

For small changes of the formula I often edit the #+TBLFM: line
directly. If things went more complex or get messed, I press C-c' to
enter the formula buffer. However, at this time my pointer is located at
the #+TBLFM: line.

The associated call function for C-c' is:

org-edit-special

This function calls

org-table-edit-formulas

in case the point is located inside the table and

ffap aka find-file-at-point

in all other cases (omitting the cases for source code and include lines
here for simplicity)

Thus pressing C-c' at #+TBLFM ends up with the request for a file or a URL.

In my opinion org-edit-special needs another case to look out for
#+TBLFM or resp. combine this with the case to call
`org-table-edit-formulas'.

Please find below a patch for that.

This is my very first public org-mode patch and my very first hack in
vital org-mode elisp code. Thus, don't laugh or blame to much.... :)
