xmlparse_GetInputContext doesn't adjust the bounds of the 
substring it returns, leading to the python string result hanging off 
one or more ends of the buffer & associated nastiness.

2 line fix attached.

Thanks for the patch. This was just resubmitted as #1118602,
which I have
applied. Your patch also checks whether offset is negative;
I believe this cannot happen.

Committed as

pyexpat.c 2.90 and 2.89.2.1
NEWS 1.1264 and 1.1193.2.31

Sorry this took so long; it would have caught my attention
earlier if it was in the patches tracker, not the bugs tracker.
