Leonid Lisovskiy 1538c975ec testsuite: typo in tr.tests
Hi

tr.tests script from bb 1.17 testsuite has wrong "optional"
conditional clauses. As result, some tr tests was skipped even if
CONFIG_FEATURE_TR_CLASSES=y. Patch attached fixes problem for me.

# This file defines two functions, "testing" and "optional"
# and a couple more...
# The following environment variables may be set to enable optional behavior
# in "testing":
# VERBOSE - Print the diff -u of each failed test case.
# DEBUG - Enable command tracing.
# SKIP - do not perform this test (this is set by "optional")
#
# The "testing" function takes five arguments:
# $1) Test description
# $2) Command(s) to run. May have pipes, redirects, etc
# $3) Expected result on stdout
# $4) Data to be written to file "input"
# $5) Data to be written to stdin
#
# The exit value of testing is the exit value of $2 it ran.
#
# The environment variable "FAILCOUNT" contains a cumulative total of the
# number of failed tests.
# The "optional" function is used to skip certain tests, ala:
# optional FEATURE_THINGY
#
# The "optional" function checks the environment variable "OPTIONFLAGS",
# which is either empty (in which case it always clears SKIP) or
# else contains a colon-separated list of features (in which case the function
# clears SKIP if the flag was found, or sets it to 1 if the flag was not found).
