Alberto Bertogli 948cee1ce1 Improve bash quoting, and other similar best practices
This patch updates the shell scripts with some of the common best
practices, which should make them more resilient to unusual failures and
unexpected environments (in particular, directories with spaces).

Most of these were identified by shellcheck.

# This test checks that we can send and receive mail to/from exim4.
#
# Setup:
# - chasquid listening on :1025.
# - exim listening on :2025.
# - hosts "srv-chasquid" and "srv-exim" pointing back to localhost.
# - exim configured to accept all email and forward it to
# someone@srv-chasquid.
#
# Test:
# msmtp --> chasquid --> exim --> chasquid --> local delivery
#
# msmtp will auth as user@srv-chasquid to chasquid, and send an email with
# recipient someone@srv-exim.
#
# chasquid will deliver the mail to exim.
#
# exim will deliver the mail back to chasquid (after changing the
# destination to someone@chasquid).
#
# chasquid will receive the email from exim, and deliver it locally.
