[AD] excustom change + d_edit_proc

[Elias Pschernig <elias@xxxxxxxxxx>]

The attached patch moves the font change code from exgui to excustom,
and also fixes the d_edit_proc overflow in it.

I found the old thread about d1 in the archives, with ideas like using
negative numbers for max_chars, or a pointer to a triplet of {max_chars,
max_bytes, max_pixels} - but apparently no idea was considered to work
very good - therefore I propose to add this note to the docs for now:
