The current GString implementation is meant to be used where buffer
overflows are a problem - when one is taking bits of strings, adding
characters, etc.  When you are just passing around strings, overflow
is not a problem, so one might as well pass a char *.

There are a few missing functions that we need to add to make GString
really useful - the one I tend to miss is:

 g_string_insert_n (GString *string, gchar *new, gint n);
But I don't think we need to wrap every single thing that you can do
with a char * with a GString.  The conversions are easy enough.

Conversion from GString => gchar *

Conversion from gchar * => GString

 g_string_new (str);

It's not like GTK+ is very heavy on string manipulation.
A lot (though not all) of the places that could 
benefit from GString do use it.
