bug#9237: [PATCH] tests: get rid of obsolete 'error_' shell function

[Stefano Lattarini]

 $ cd ~/src/coreutils
 $ grep -I -r --exclude-dir=.git '\berror_\b' .
 ./tests/shell-or-perl:error_ ()
 ./tests/shell-or-perl:  test $# -gt 1 || error_ "option '\''$1'\'' requires an 
argument"
 ./tests/shell-or-perl:    -*) error_ "unknown option '$1'";;
 ./tests/shell-or-perl:  0) error_ "missing argument";;
 ./tests/shell-or-perl:  || error_ "test script '$test_script' does not exist, 
or isn't readable"
 ./tests/shell-or-perl:  || error_ "cannot read from the test script 
'$test_script'"
 ./tests/shell-or-perl:error_ "dead code reached"
 ./tests/init.cfg:# FIXME: eventually s/error_/fail_/ and remove the definition 
of error_ below.
 ./tests/init.cfg:    error_ "Error running getlimits"
 ./tests/init.cfg:error_() { echo "$0: $@" 1>&2; Exit 1; }
 ./tests/init.cfg:framework_failure() { error_ 'failure in testing framework'; }

So, time to remove dead code, right? :-)

What about the attached patch?

Regards,
  Stefano

Subject: [PATCH] tests: get rid of obsolete 'error_' shell function

* tests/init.cfg (framework_failure, getlimits_): Use 'fatal_'
instead of 'error_'.
(error_): Delete, it's not used anymore (and one is anyway
advised to use 'fatal_' instead).
Update heading comments.
* tests/shell-or-perl (error_): Renamed ...
(fatal_): ... to this, for consistency.  Also, add a useful
comment.
