I can understand and sympathize with this point of view. But, from my
point of view as someone writing cross-platform POSIX shell programs,
this is a legitimate compliance bug that breaks scripts running under
'set -C' that should be expected to work according to the standard. (It
has done in at least one real-life case, i.e. mine). A shell-specific
workaround ought not to be necessary for this. If the goal of 'emulate
sh' is to provide a compatible POSIX environment then this situation is
clearly inconsistent with that goal. So I hope you're willing to
reconsider and think of a solution -- perhaps a SH_APPEND shell option
(which would also apply to ksh emulation).

Thanks,
