Oh, sorry, I forgot to send suggestions for commit log entries when I
sent that lot of updates...
That one makes this patch sound much more important and substantive than
it really is - what the log message there says was already done in the
shell. All the patch does is make the initial value of the F flag reflect
That is, now you can tell if your shell was compiled without vfork()
support (if for some reason you care) by seeing whether F appears in
the value of $- (when nothing has contrived to change it, so using
a command something like)
ENV=/dev/null sh -c 'echo $-'
would do it.
