That reminds me why my :override advice was simpler.  Indeed, I had to
get rid of that test to ensure that the function would work as intended
for remote shell buffers.  It never made much sense IMO and I got the
impression that it is in place as a "let's be absolutely sure" measure.
I can say that I face no issues with the test omitted thus far. It could
be a product of me being in control of $PS1 for local and remote shells
though.
