Oops. I misquoted the code (because I had submitted the report after I
had made/tested/byte-compiled/over-writte my only local copy). If you look at 
the
code on the gnu cgit instance, at line 1907, you'll see that it adds one
to the line-end-position before passing the value the function
delete-region.

A similar idiom exists on line 1843, so that may be another bug.
