Invocation is probably very relevant. Looking at the bash man page:
When invoked as sh, bash enters
posix mode after the startup files are read.
the -e option is given, interpretation of the fol-
lowing backslash-escaped characters is enabled.
The -E option disables the interpretation of these
escape characters, even on systems where they are
interpreted by default.
I can't find any mention of what systems do what by default; presumably
that's determined at compile-time.
The implication being that if it doesn't interpret escapes when invoked
as "sh", it's probably a bug. If it's invoked as "bash", it can do what it
likes, depending on the system.
