Bug#815234: detect Rdata files with embedded code

[Daniel Pocock <daniel@pocock.pro>]

package: lintian
version: 2.5.41
severity: wishlist

Many R modules (packages named r-cran-*) contain some data files with
names like

*.rda
*.Rda
*.rdata
*.Rdata

This file format can contain data or code.

A lintian check should try to determine if any code is embedded in the
file and if so, emit an error, as this would never be acceptable in Debian.
