Error messages for fatal error e.g. ${x?foo} or rovar=foo or

"environment:" instead of "scriptname:" (or "$0:").
Thanks for the report. Error messages during function execution display the
source file where the function is defined. When there's no source file,
such as -c command or when reading a script from stdin, the shell defaults.
We can do a little better job of defaulting here.
