doc/guix.texi (G-Expressions): Document the use of assume-valid-file-name with
local-file.

Hi Guix!

+@var{file} can be wrapped in the @code{assume-valid-file-name} syntactic
+keyword. When this is done, there will not be a warning when
+@code{local-file} is used with a non-literal path. The path is still

+Wrapping is done like this:

+(local-file (assume-valid-file-name alice-key-file-path))

This is the declarative counterpart of the @code{interned-file} monadic
procedure (@pxref{The Store Monad, @code{interned-file}}).
