pango -- prevent line break?

[Allin Cottrell <cottrell wfu edu>]

I have some text I'm displaying via pango and while in general 
I want to allow automatic line breaks, I want to prevent line 
breaks from occurring in certain contexts.

Specifically, what I'm trying to avoid is the breaking of 
option-flag strings such as "--quiet" in online documentation 
(with "--" appearing on one line and "quiet" on the next).

I've tried creating a GtkTextTag like this:

    tag = gtk_text_tag_new("optflag");
    g_object_set(tag, "family", "monospace",
                 "wrap-mode", GTK_WRAP_NONE,
                 "wrap-mode-set", TRUE, NULL);

then adding it to the appropriate GtkTextTagTable, and using 
gtk_text_buffer_insert_with_tags_by_name to wrap the option 
strings. But, alas, it doesn't help: the monospace font is 
applied OK, but I still get line breaks after "--".

Any suggestions would be appreciated.
