Filter out _AST_FEATURES when comparing environment state. (#110283)zack/bug-110283
ksh93 uses an environment variable called _AST_FEATURES to communicate
with subshell instances of itself. Its value may change at any time
so AT_CHECK_ENV should ignore it.
This was responsible for many spurious testsuite failures on
OpenIndiana. Problem reported by Bob Friesenhahn.
* tests/local.at (_AT_CHECK_ENV): Add _AST_FEATURES to list of
variables set by shells to unstable values.
