I'm surprised that in both yours and the original that we do not need to
subtract 3 from "size".
It looks like we advance "entry" here, not "buf", and then iterate over
"buf". But I think that makes the later logic weird:
if (entry != buf + i && entry[0] != '#')
because if there is a BOM, we end up with "entry > buf + i", which I
think this code isn't expecting. I'm not sure it does anything bad, but
I think it might be simpler as just:
/* save away the "real" copy for later, as we do now */
el->filebuf = buf;
/*
* now pretend as if the BOM was not there at all by advancing
* the pointer and shrinking the size
*/
skip_utf8_bom(&buf, &size);
/*
* and now we do our usual magic with "entry"
*/
entry = buf;
for (i = 0; i < size; i++)
