I would like to apply only this small patch for editcmd.c.

Justification for the use of GString
====================================

I like the data type GString because it is already available in glib-1.2 
as well as glib-2.0, it is easy to use, and you don't have to worry 
about the maximum length of your strings.

from src/subshell.c:694:
    /*
     * Factor 5 because we need \, 0 and 3 other digits per character
     * in the worst case (tcsh and zsh).
     */
    d = ret = g_malloc (5 * strlen (s) + 16);

This could be changed to:

     ret = g_string_new ("");
     ...
     g_string_appendc (ret, 'x');
     g_string_append (ret, "foobar");

Another feature is that getting the string's length will have a time 
cost of O(1), while the strlen() function has a time cost of O(strlen(s)).
