Hi,
I observed a slight problem in deparse(): it will add spaces around
most operators except /. I wonder if this is easy to fix. I know this
is quite trivial, but I will appreciate if / is not treated as an
exception. Examples:
It's easy to change: take a look at src/main/deparse.c. The operators
that are labelled as PP_BINARY2 get no spaces. Looking in
src/main/names.c, we see those are /, ^, %%, %/% and :.
But clearly this is by design, and I think it's unlikely to change.
