XX-XX-XX A bug was fixed which caused ksh93 to close shp->pwd
prematurely for the last command executed by the shell
(close-on-exec).
I refrain from using more explicit language to describe what this bug did to us.
I'd also like to request to change this entry:
13-05-22 +Added -c option to typeset which is similar to typeset -m except
that the variable is copied rather than moved. This is experimental
and there are known bugs. If it can't be made reliable it will
not be added.
and remove the 'This is experimental.*it will not be added.' part.
IMO typeset -c has proven its usefulness. The remainder is just fixing
all damn bugs.
