As described in commit v9.10-283-g5cb0cca3b avoid using ulimit with $SHELL -c, and explict invocation of the shell like that can require lots of memory, often due to loading the locale archive. * tests/basenc/bounded-memory.sh: Avoid $SHELL -c with ulimit. * tests/cut/bounded-memory.sh: Likewise. * tests/expand/bounded-memory.sh Likewise. * tests/pr/bounded-memory.sh Likewise. * tests/unexpand/bounded-memory.sh Likewise. * tests/fold/fold-zero-width.sh: Bring the ulimit bound down to the standard 6M over the determined limit.
