Fix typo “a Rc” → “an Rc” (and a few more) After stumbling about it in the dev-guide, I’ve devided to eliminate all mentions of “a Rc”, replacing it with “an Rc”. E.g. ```plain $ rg "(^|[^'])\ba\b[^\w=:]*\bRc" compiler/rustc_data_structures/src/owning_ref/mod.rs 1149:/// Typedef of a owning reference that uses a `Rc` as the owner. library/std/src/ffi/os_str.rs 919: /// Converts a [`OsString`] into a [`Rc`]`<OsStr>` without copying or allocating. library/std/src/ffi/c_str.rs 961: /// Converts a [`CString`] into a [`Rc`]`<CStr>` without copying or allocating. src/doc/rustc-dev-guide/src/query.md 61:are cheaply cloneable; insert a `Rc` if necessary). src/doc/book/src/ch15-06-reference-cycles.md 72:decreases the reference count of the `a` `Rc<List>` instance from 2 to 1 as library/alloc/src/rc.rs 1746: /// Converts a generic type `T` into a `Rc<T>` ``` _(the match in the book is a false positive)_ Since the dev-guide is a submodule, it’s getting a separate PR: rust-lang/rustc-dev-guide#1191 I’ve also gone ahead and done the same search for `RwLock` and hit a few cases in the `OwningRef` adaption. Then, I couldn’t keep the countless cases of “a owning …” or “a owner” unaddressed, which concludes this PR. `@rustbot` label C-cleanup
