I am pretty sure this is a bad idea. You might have a stack of a dozen
errors in your iESS. How would you highlight links to those errors if
everything else is red?

Currently are red, non-intrusive and with clear separation between links:

All of that will be lost withing a red paragraph. I don't know how
R-Studio handles that but it looks like this particular thing is one fat
minus of their design.
