ebcea98eca Fix problem with ERR_RETURN. 
It wasn't suppressed properly in the code following an if
in some circumstances, in particular in initialsation scripts
and also in a nested function where the caller had suppressed
it.

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.

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.

af1c82d646 40173: Off-by-one error checking for {varid}.

641a764b82 users/22688: Allow mixing redirs and arguments after anon functions.

can't take normal arguments at that point.

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.

Add test.

d7110d8f01 41012: Fix premature exit from nested function in EXIT trap. 
Also add check so we don't delay an exit if we were already in

immediately.

47c05f6b66 40622 with typos fixed: functions -Ms. 
This adds the capability for mathematical functions based on shell
functions to have a string argument.  Module functions have had
this for a long time.
