rustfmt keeps reformatting C-style doc comment

[davepacheco]

Using this version of rustfmt:

$ cargo +nightly fmt -- -V
rustfmt 1.4.11-nightly (18382352 2019-12-03)

and starting with this file:

/** foobar */
const foo: u32 = 0;

I find that rustfmt keeps adding asterisks to the end of the comment. If I keep re-running rustfmt, I get more asterisks:

$ cat src/dummy.rs 
/** foobar */
const foo: u32 = 0;
$ cargo +nightly fmt -- src/dummy.rs 
$ cat src/dummy.rs 
/** foobar **/
const foo: u32 = 0;
$ cargo +nightly fmt -- src/dummy.rs 
$ cat src/dummy.rs 
/** foobar * **/
const foo: u32 = 0;
$ cargo +nightly fmt -- src/dummy.rs 
$ cat src/dummy.rs 
/** foobar * * **/
const foo: u32 = 0;
$ cargo +nightly fmt -- src/dummy.rs 
$ cat src/dummy.rs 
/** foobar * * * **/
const foo: u32 = 0;
$ cargo +nightly fmt -- src/dummy.rs 
$ cat src/dummy.rs 
/** foobar * * * * **/
const foo: u32 = 0;
$ cargo +nightly fmt -- src/dummy.rs 
$ cat src/dummy.rs 
/** foobar * * * * * **/
const foo: u32 = 0;
$

@davepacheco I was not able to reproduce this locally. Are you using any configuration option?

Sorry for leaving that out! I see this with a rustfmt.toml that contains only wrap_comments = true. I do not see this with default options.
