[PATCH] Remove note about C++ demangler from Rust documentation

[PATCH] Remove note about C++ demangler from Rust documentation

[Tom Tromey]

A note about the C++ demangler in the Rust documentation hasn't been
accurate for a while.  Also, it probably isn't clear to users how this
related to the next bit of text in the same bullet point.  This patch
removes the obsolete comment.
