# AT_CHECK(COMMANDS, [STATUS = 0], STDOUT, STDERR)
# ------------------------------------------------
# Execute a test by performing given shell COMMANDS.  These commands
# should normally exit with STATUS, while producing expected STDOUT and
# STDERR contents.
#
# STATUS, STDOUT, and STDERR are not checked if equal to `ignore'.
#
# If STDOUT is `expout', then stdout is compared to the content of the file
# `expout'.  Likewise for STDERR and `experr'.
#
# If STDOUT is `stdout', then the stdout is left in the file `stdout',
# likewise for STDERR and `stderr'.  Don't do this:
#
#    AT_CHECK([command >out])
#    # Some checks on `out'
#
# do this instead:
#
#    AT_CHECK([command], [], [stdout])
#    # Some checks on `stdout'
#
# This is an unfortunate limitation inherited from Ultrix which will not
# let you redirect several times the same FD (see the Autoconf documentation).
# If you use the `AT_CHECK([command >out])' be sure to get a test suite
# that will show spurious failures.
#
# You might wonder why not just use `ignore' and directly use stdout and
# stderr left by the test suite.  Firstly because the names of these files
# is an internal detail, and secondly, because
#
#    AT_CHECK([command], [], [ignore])
#    AT_CHECK([check stdout])
#
# will use `stdout' both in input and output: undefined behavior would
# certainly result.  That's why the test suite will save them in `at-stdout'
# and `at-stderr', and will provide you with `stdout' and `stderr'.
#
# Any line of stderr starting with leading blanks and a `+' are filtered
# out, since most shells when tracing include subshell traces in stderr.
# This may cause spurious failures when the test suite is run with `-x'.
#
#
# Implementation Details
# ----------------------
# Ideally, we would like to run
#
#    ( $at_traceon; COMMANDS >at-stdout 2> at-stderr )
#
# but we must group COMMANDS as it is not limited to a single command, and
# then the shells will save the traces in at-stderr. So we have to filter
# them out when checking stderr, and we must send them into the test suite's
# stderr to honor -x properly.
#
# Limiting COMMANDS to a single command is not good either, since them
# the user herself would use {} or (), and then we face the same problem.
#
# But then, there is no point in running
#
#   ( $at_traceon { $1 ; } >at-stdout 2>at-stder1 )
#
# instead of the simpler
#
#  ( $at_traceon; $1 ) >at-stdout 2>at-stder1
