bbccbe0c85 43660: extend 43653 when final exit is implicit. 
Combine logic for case after committed to exit (shell_exiting) with

Add sarky note for future generations to be confused at.

0a20f4e5a6 43535: Fixes for bg / fg handling of superjobs. 
Be more consistent about marking both superjob and subjob as
running when sending SIGCONT.

Send SIGCONT to superjob / subjob combination any time it is put
in foreground, even if thought running, since subjob may invisibly
have suspended.

When waiting for superjob, wait for subjob, too.

0d5275c6b9 43409: Fix process group setting in main shell. 
A newly forked subshell now reports back the process group it
will be using for the main shell to record.

This prevents an error where the shell incorrectly thought an
exiting process owned the terminal and so grabbed it back,
putting the foreground process into the background.

faf0035e53 unposted (branch fork_early): Fork early for pipelines. 
If executing a command not at the end of a pipeline, and
not optimised in the calling code, we can fork before
"prefork" substitutions, at the same point as
for background commands.

Move fork before our preliminary scan of arguments to find
a command: in the cases of early fork
we don't need this information before forking.

Ensure we _exit if forked in execcmd_exec().

Rationalise use of forks and pipes.

Ensure we _exit instead of returning from execcmd_exec() if we
have forked.  Before the optimisation code after the fork always ran
to the check at the end, but that code is overkill for the logic
between the early fork and the existing one.

Remove old workaround to fork in caller of execcmd for current shell
constructs as no longer needed with early fork below.

Close input of newly created pipe on fork (destined for RHS of pipe
which we never execute): this replaces a workaround from
zsh-workers/32171, commit 9887fc3d7b.

Set last1 on early fork as needed by some instances of shell
constructs on LHS of pipeline to know they are exiting.

9e2afb9298 42684 (with extra comments): Fork early if in bg. 
In execcmd the case of running the last command in a pipeline
asynchronously for the purpose of & and &! is easy to work out,

the parent shell by forking earlier.

94014ff65b 41113 (tweaked): Save current line linkage to history ring. 
When saving history state save whether the current history line

later.  This avoids surprises where the history ring is freed
and incorrectly frees the current state in curline, which has
a different allocation strategy.

Original patch tweaked to make restoring more logical.
