I have a strange problem (which is only a minor annoyance so not deal
breaking): the fontification of src blocks differs from what it looks
like when editing the src block.

See attached image and, specifically, the "The" immediately after the
single quote in the first line.  It is correctly coloured in the edit
window but not in the original org file (whether being edited or not).

Any ideas?

Thanks,
eric
