Subject: Add a set_unsaved method.
X-Git-Tag: v0.7.3~294
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=23a109b05ec5e76c4f629338dcaafedbf1e8954b;p=pspp-builds.git

Add a set_unsaved method.

Added a psppire_window_set_unsaved method, which can be
used to indicate that the contents of a window has been
modified since it was last saved.
Use this method for the syntax window.
