Ada mode auto-casing changed behaviour after 24.4

[Alberto]

Hi,

I noticed a change is behaviour for Ada mode auto-casing.

Until 24.3, auto-casing enabled with capitalize-word would have changed:
    counter_array
to
    Counter_Array

Now, it changes it to:
    Counter_array -- note the A after _ is not capitalised any more.

It may seem a small thing, but it breaks my coding standards and looks odd
on existing code.

Has anybody experienced the same?
Any idea on how to restore the old behaviour?

Many thanks,
Alberto
