*** New package osc.el.
*** New package ansi-osc.el.
Support for OSC ("Operating System Command") escape sequences has been
extracted from comint.el in order to provide interpretation of OSC
sequences in compilation buffers.
Adding the new function 'osc-compilation-filter' to
Adding the new function 'ansi-osc-compilation-filter' to
'compilation-filter-hook' enables interpretation of OSC escape
sequences in compilation buffers. By default, all sequences are
filtered out.
