No, the reason for the change is not there, but in ispell.el 1.244

* textmodes/ispell.el (ispell-find-aspell-dictionaries): ...
Use correct dictionary alist for default.

if, as I guess, you use aspell.

As a matter of fact, you should have found the behavior you currently find
until ispell.el 1.228 (Thu Apr 24 2008). Before that, if an english aspell
dict was found, it was made the default, otherwise first entry in
ispell-dictionary-alist-1 was used. When moving to the new scheme, the alist
name was not updated, so ispell.el tried first to find 'en' in the original
alist, not in the aspell dicts alist, and since it was never found there
the fallback first entry was always used for default.

In the above change, 'en' is now found in the correct alist, so if an english
dict is installed it is used as default. Note that this change did nothing
else than making the code work as expected.

There is room for discussion about what should be 'expected'. I am beginning
to think that we should just set aspell default as the current fallback
default, without trying english first.

If there are no objections, I will commit attached patch. As a matter of
fact 'en' precedence did not work for a long time and there were no
complaints about that.
