[ESS] Backtick and font locking mystery

[Patrick Connolly]

If I do something like this:

> system("rm non.existing.file")
rm: cannot remove `non.existing.file': No such file or directory
> 

as one would expect.  However, the backtick screws up the font
colours.  Deleting it fixes everything (even though the single quote
isn't matched anywhere).

I didn't have this problem until about ESS 3.3.2 or so.  However, it
might be that bash changed this detail at that time, a detail I didn't
notice at the time, but somehow, I doubt it.

I thought I'd get round it by doing this:

> try(system("rm non.existing.file"), silent = TRUE)

But it's not silent anyway for this kind of error, so that got me
nowhere.

Other ideas are welcome.

TIA
