CVS commit: src/bin/sh

["Robert Elz" <kre%netbsd.org@localhost>]

Module Name:    src
Committed By:   kre
Date:           Fri Aug 19 12:52:32 UTC 2022

Modified Files:
        src/bin/sh: miscbltin.c

Log Message:
Don't output the error for bad usage (no var name given)
after already writing the prompt (set with the -p option).

That results in nonsense like:

        $ read -p foo
        fooread: arg count

While here, improve the error message so it means something.

Now we will get:

$ read -p foo
read: variable name required
Usage: read [-r] [-p prompt] var...

[Detected by code reading while doing the work for the previous fix]
