Bug report for pretty-printing coprocesses with simple commands

[Seth Sabar]

Hi,

I'd like to report a bug with the *--pretty-print* feature of bash. When I
run the following script:

*coproc sleep 5*

the pretty-printed result is

*coproc COPROC* sleep 5

The reason this happens is because within Bash's AST every *coproc* is
given a name regardless of whether the user specifies one and the default
is *COPROC*. However, per the bash manual only *coproc*s followed
*compound-command*s may have names. I believe this issue can be fixed in
*make_command_string_internal* in the case handling *cm_coproc* there
should be different cases based on what type of *command* it contains.

I discovered this issue via *coproc.tests* in *bash-5.2/tests/*.

Best,
Seth
