In the *response* buffer the cursor is not visible, but can be moved as expected.

Certain complex response from the prover (Isabelle2007) can make font-lock crash when processing the output for display in *response* buffer. The included file "bad.output" has been fetched from the *isabelle* buffer in the critical situation. It can be replayed by starting a fresh Isabelle2007 / Proof General session on Cygwin and issuing the following Isar command:

ML {* Output.std_output (File.read (Path.explode "bad.output")) *}

This will result in tons of messages like this:

(1) (error/warning) Error in process filter: (args-out-of-range *response* 330313 345908)

(2) (error/warning) Error in process filter: (args-out-of-range *response* 314717 330312)

(3) (error/warning) Error in process filter: (args-out-of-range *response* 299121 314716)

(4) (error/warning) Error in process filter: (args-out-of-range *response* 283525 299120)

The problem seems to be specific to Cygwin or the particular XEmacs 21.4.20 installation of that distribution. It works fine on various Linux installations of with XEmacs 21.4.21/22.

At some point (I think related to emacs 24) Proof General changed its way for indenting lines under quantifiers. E.g.

Lemma foo_bar_baz : forall x y z,

x = y -> y = z -> x = z.

Is there a way to revert to the previous 2-space indent from the indent at the beginning of the line?
