In order to check for &&-chain breakage, each time TestParser encounters
a new command, it checks whether the previous command ends with `&&`,
and -- with a couple exceptions -- signals breakage if it does not. The
first exception is that a command may validly end with `||`, which is
commonly employed as `command || return 1` at the very end of a loop
body to terminate the loop early. The second is that piping one
command's output with `|` to another command does not constitute a
&&-chain break (the exit status of the pipe is the exit status of the
final command in the pipe).
However, it turns out that there are a few additional cases found in the
wild in which it is likely safe for `&&` to be missing even when other
commands follow. For instance:
while {condition-1}
do
test {condition-2} || return 1 # or `exit 1` within a subshell
more-commands
done
while {condition-1}
do
test {condition-2} || continue
more-commands
done
Such cases indicate deliberate thought about failure modes by the test
author, thus flagging them as breaking the &&-chain is not helpful.
Therefore, take these special cases into consideration when checking for
&&-chain breakage.
