Good and bad news. I repeated the test carefully looking around for old
abbrev.el or .abbrev_defs file.

    1. Good, I can confirm that your patched abbrev.el works in the
       sense that write-abbrev-file does not destroy the properties of
       the table.

    2. However I tried to add a local abbrev (or an inverse local
       abbrev) in the fundamental mode, but I obtain 

obarray-get: Wrong type argument: vectorp, ([## 0 0 0 0 0 0 0 0 0 ...] [## 0 0 
0 0 0 0 0 0 0 ...]) [2 times]

That is maybe the reason I run into difficulties if I want to use
flyspell's abbrev mode if a correction occurs.

Uwe
