I'm coming across some code that uses the fact the parser ignores a

x = "abc \

identical(x, y)
# [1] TRUE
However:
identical("\\n", "\n")

I'm still hung up on ?Quotes -- I can't see mention of 'newline' as a
valid escape. It mentions the literal sequence '\' 'n', where 'n' is
being escaped.
Glanced at the parser blame and apparently the terminal '\' is the
older behavior, and what I'm used to, i.e. literal newlines in char
constants
