7d1877da4e 41608 (plus tests): restore ERR_EXIT before function. 
There was an exception to the usual ERR_EXIT pattern that causes
problems when executing a function in an else branch.  It seems
the exception is no longer needed as the regression tests pass
without it.

97d4bdbc7e 41590 modified as 41595: make ERR_RETURN more logical. 
It now operates separately at each function depth.

To keep ERR_EXIT global, make the noerrexit variable usd bit flags.

Extend tests.

ddb8675901 posted but has not shown up: fix fd problem in subshell. 
Record fd's that have been saved in fdtable and if the shell
forks close them as they will never be restored.

74aff4106a 41542: Fix pcre logic for extracting matched parentheses. 
When we went off the end of the array but measured the length
implicitly, we got lucky before.  After 41308 we were looking up lengths
in stale memory.

Rename some variables, clean up the logic, be easier to understand.

Add tests.

2eacbef919 41499 (with one further tweak): POSIX_STRINGS behaviour. 
Ignore a terminating delimiter when splitting as separators
despite being called separators are terminators.

a955065cda Delay processing "disown" for superjob. 
This is a job forked from the current shell when a job partly
running from the current shell was suspended.  When all associated
processes started from the main shell are finished the job is
continued and at this point the disown can complete.

ae10f88bfb 41386: when backgrounding a STAT_CURSH job, remove the flag. 
This typical applies to a STAT_SUPERJOB.  It prevents it from
getting copied interrupts as a foreground process.

151a4660e2 41164: Don't free a history entry if it's curline. 
This replaces 41113 / 94014ff65b with a simple local change for the
immediate problem.  It's not entirely clear if this reflects wider
changes in the structure of the history code.

94014ff65b 41113 (tweaked): Save current line linkage to history ring. 
When saving history state save whether the current history line
is linked into the ring and remove it, and restore as appropriate
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.

4bb81eefbd 41096: Don't assume null termination copying string. 
At this point the string may contain embedded nulls or not have
a null termination at all.

Also, as we always have the length memcpy() is more efficient.

f25d01a97c Fix combination of HERE document and |&. 
A missing flag setting up the HERE document mean that the size
of the wordcode needed to append the 2>&1 was counted incorrectly,
so the resulting wordcode was garbled.

immediately.
