Hexadecimal WINDOWID breaks w3m-img

[Paride Legovini]

The w3m-img browser has the ability to show images in a terminal. This is used for example by the ranger[1] file manager to preview image files (see [2] for an example). This works fine in xterm, but does not work with sakura. It turns out that xterm saves the WINDOWID variable as a decimal numer:

$ echo $WINDOWID
67108879

while sakura as a hexadecimal number:

$ echo $WINDOWID
0x3e00003

Converting WINDOWID from hexadecimal to decimal, for example like this:

$ export WINDOWID=$(($WINDOWID))
$ echo $WINDOWID
65011715

fixes the issue: w3m-img works fine in sakura too. Permanently fixing this should be as easy as changing sakura.c:2800 from

gchar *winidstr = g_strdup_printf ("0x%x", winid);

to

gchar *winidstr = g_strdup_printf ("%d", winid);

Please consider applying this simple patch.
The credit for the workaround goes to [3].
