# Portability notes:
# - Avoid set -e given its ambiguous interaction with subshells.
# - Not all shells update $PWD as required by POSIX.
# Use the pwd builtin instead.
# - Command substitution strips all trailing newlines.
# Preserve trailing newlines by appending a safety character and then
# removing it with parameter substitution, along with the newline
# appended by pwd itself.
