Hi Eric,
thanks for your report and careful observations.

First of all, if anything goes wrong with table realignment, you can
always force a realign of the table with C-c C-c which in Org-mode
generally has the meaning of "update" (exception: tags).
The org-mode table editor works by re-aligning the table each time you
press TAB or RET in a table. When the tables get large, this constant
re-aligning does get kind of slow, so the table editor tries to be
really smart and do the re-alignment only if necessary. For example,
it inserts and deletes characters in table fields, and if the column
width is not affected, it does not trigger a re-align. And it also
tries to re-insert new rows without triggering a re-align. This has
worked really well so far, but indeed with hiding of link text the code
inserting a new row without triggering re-align is broken. For now I
will fix it by triggering a re-align whenever a new line is inserted.
When I get around to it I will fix the insertion code (which is a bit
more complicated.
The reason why leaving the table, doing a buffer modification, getting
back into the table and pressing TAB fixes the indentation is precisely
because then Org-mode know the buffer has changed and a re-align might
be necessary, so it triggers one.

Yes, this is fully independent.

I have tried quickly and not seen a problem with 3.6 - but I did not
test exhaustively.

This is interesting, but right now I don't know how to fix this. Hmmm.
I guess this really is an Emacs bug.
> ** Observation: TODO sequences and dynamic setting of org-todo-keywords
When starting Org-mode, a number of regular expressions are computed
and set. Among others, there are the regular expressions matching the
TODO keywords and other settings. When you change the settings while
Emacs is running, these expressions need to be re-computed. M-x
normal-mode does simply restart Org-mode and trigger this. For the
same money you could do M-x fundamental-mode and then M-x org-mode.
The only way to avoid this would be to compute the regular expressions
again before each command using them, which I find not acceptable.
The best way to experiment with TODO keywords in *not* putting Lisp
code into the buffer and eval it with eval-region. It is much better
to use
#+TYP_TODO: TODO WAITING DONE
in the buffer and then press C-c C-c when you have changed one of those
lines to update.

I don't think this is true, is it? Which specifications?

I have tried to explain this well in the documents, but I guess it can
be improved. Yes I am not saying much about the "why", but you are the
first to care :-)
I'll take another look at the documentation and see if this can be
improved.
