Precondition: A java source file (/tmp/foo.java) containing the
following function (use spaces - not tabs):
public void a(
int b,
int c,
int d,
int e,
int f,
int g,
int h,
int i,
int j,
int k // comment
)
{
}
Start Emacs using 'emacs -Q' and enter the following:
C-x C-f /tmp/foo.java RET
M-x which-function-mode
Emacs freezes for a couple of minutes.
