# ==== Purpose ====
#
# Verify that the "escape" function in the mysqltest language works as expected.
#
# ==== Requirements ====
#
# R1. escape(C,S) shall insert a backslash character before every occurrence
# of C in S and return the resulting string.
# R2. escape(C,S) shall preserve leading and trailing whitespace in S.
# R3. escape(C,S) shall work if S is empty.
# R4. escape(C,S) shall work when C or S contains parentheses or commas, and
# when S contains newlines.
# R5. escape(C,S) shall work when C is multi-character.
# R6. escape(C,S) shall fail when C is newline.
# R7. escape shall fail when the parentheses or comma are wrong.
