** Function arguments in *Help* buffers are now shown in upper-case.
Customize `help-downcase-arguments' to t to show them in lower-case.
** Delete Auto Composition Mode. Now the variable
`auto-composition-mode' is simply a buffer local variable. The
commands `auto-composition-mode' and `global-auto-composition-mode'
still works as before.
