Is there any reason not to preserve it?

Thanks, the bash manpage indeed references:

http://tiswww.case.edu/php/chet/bash/POSIX

(btw: would it make sense to add this as a manpage, e.g. as bash-posix?)

The relevant point seems to be:

 36. Subshells spawned to execute command substitutions inherit the
     value of the `-e' option from the parent shell.  When not in POSIX
     mode, Bash clears the `-e' option in such subshells.

Now I'm still curious why this isn't the default behaviour in bash?

Thanks,
Chris
