* tests/test-lib.sh (Exit): New function by Ralf Wildenhues in automake http://git.sv.gnu.org/gitweb/?p=automake.git;a=commitdiff;h=20594c08f63 * tests/**: Convert all uses: This restrictive change converted the vast majority: git grep -l '^(exit \$fail); exit \$fail$' \ | xargs perl -pi -e 's/'^\(exit \$fail\); exit \$fail$/Exit \$fail/' And this did the rest, plus a few undesirable ones, so I manually backed out the changes to ChangeLog-* and build-aux/check.mk: git grep -l -E '\(exit [^)]+\); exit ' \ | xargs perl -pi -e 's/\(exit (.+?)\); exit \1/Exit $1/'
