packets that are currently being displayed from that capture. Centralize the code to control whether "File:Save" and "File:Save As" are enabled (and *always* have "File:Save As" enabled if you have a capture; "File:Save" is enabled only if you have a live capture you've not yet saved, although it does the same thing as "File:Save As"). Have the "save_file" member of a "capture_file" structure represent *only* the file currently being *written* to by a capture, and, if there is no capture currently in progress, have it be NULL; the name of the file currently being *displayed" is in the "filename" member, and an "is_tempfile" member indicates whether it's a temporary file for a live capture or not. Have "close_cap_file()" delete the current capture file if it's a temporary capture file that hasn't been saved (in its entirety - saving selected frames doesn't count). Do the same (if there *is* a current capture file) when exiting. The "Ready to load or capture" message is the only statusbar message in the "main" context; "close_cap_file()" should never pop it, it should only pop whatever message exists in the "file" context, and thus has no need to take, as an argument, the context for the message it should pop. Update the man page to reflect the new behavior of "File:Save" and "File:Save As", and to reflect recent changes to "Display:Match Selected". svn path=/trunk/; revision=1170
