# Allowed endings/separators after most commands:
# newline, comment, closing brace, semicolon, EOF
# they are also allowed after opening and closing braces themselves.
#
# Not tested here:
# r/R/w/R/e and s///[we] which use read_filename() and do not
# accept comments or semicolons.
# Test commands and braces followed by:
# closing braces, comment, semicolons, EOF (newlines are tested later).
#
# sed-4.3 wrongly rejected y/// followed by '}' or '#' (bug#22460).
#
# Implementation notes (see compile.c):
# Simple commands, '}', and 'y///' commands use read_end_of_cmd().
#
# q/Q/l/L have additional check for optional integer,
# then call read_end_of_cmd().
#
# labels use 'read_label()'.
#
# 's///' has special handling, depending on additional flags
# (with 's///[we]' commands and semicolons are not allowed).
# Implemented in mark_subst_opts().
