Problem with MXML_CUSTOM in Version mxml-2.10

[mkoennecke]

Hi,

I am using the MXML_CUSTOM element together with custom callbacks for loading and writing.
This all worked well for years but broke with version 2.10. I tracked it down to line 2928 of file mxml-file.c. In the distributed version the line reads:

if ((data = (*global->custom_save_cb)(node)) == NULL)

but it must read:

if ((data = (*global->custom_save_cb)(current)) == NULL)

With that change my code continued to work again. Please adopt my fix for version 2.11
