Perhaps a small update to ?.Renviron would be in order to mention that...
Would you have a more specific suggestion how to update the
documentation? Please note that it already says
"‘value’ is then processed in a similar way to a Unix shell: in
particular the outermost level of (single or double) quotes is stripped,
and backslashes are removed except inside quotes."
Thanks,
Tomas

Indeed quoting works! Kevin suggested the same, but he didnt reply to the list.
Thank you all!

AVAR=${APPDATA}/foo/bar
Which is a documented way of referring to existing environment
variables. Now, with that in R I'm getting:
Sys.getenv("APPDATA") # That works OK
[1] "C:\\Users\\mbojanowski\\AppData\\Roaming"
so OK, but:
Sys.getenv("AVAR")
[1] "C:UsersmbojanowskiAppDataRoaming/foo/bar"
Hmm, a function called by readRenviron does seem to remove backslashes,
but not if they are encountered inside quotes:
https://github.com/r-devel/r-svn/blob/3f8b75857fb1397f9f3ceab6c75554e1a5386adc/src/main/Renviron.c#L149
Would AVAR="${APPDATA}"/foo/bar work?
