[Patches] ircu 2.10.11: doprintf() patch

[Zoot]

ircu 2.10.11's doprintf() does not null-terminate strings generated when 
converting integers. I've only tested this patch lightly, but it should 
work.

Please let me know if you have any questions, or if Mozilla's mailnews 
client messed something up.
