[isabelle-dev] Mac OS X quit handler (COMMAND-Q)

[Makarius]

Dear all,

this is specifically for those used to be hooked to some Isabelle 
repository version, where there is also a strong correlation with Mac OS.


Officially we are now at Isabelle2013-RC2.  For the coming 
Isabelle2013-RC3, and then hopefully the final Isabelle2013, I made a 
somewhat critical change for Mac OS X / Java here:

https://bitbucket.org/isabelle_project/isabelle-release/commits/b7e7557e80b55edfbc8de8317c167ce2b1d55751

It means that closing the application should invoke the normal shutdown 
procedure of jEdit, where the user has a chance to say what to do with 
changed files.  It could also mean that Apple or Oracle will bomb the 
thing in certain situations, who knows.


See also the tracker item #2 here

(So far the tracker was de-facto a private scratchpad of myself and 
Christian Sternagel.)
