I'd like you comment on what I think is broken in our sh:
When a variable is set like:
a=`command`
all shells I know of, strip of trailing new-lines.
Our shells doesnt which breaks Pnews (at least at our site). Reason:
a sed script is evaluated and gives only empty lines to a var called
moderator. This var is then checked to be empty. this check fails.

I have a patch ready for this, but I'm not going to commit it when
ppl dont agree on this.

Please include me in the Cc: list, as I'm not on current


So, to summarize:
On a Sun, we see:
Script started, file is typescript
guido@wzv[1] cat a




guido@wzv[2] cat sh
m=`cat a`
guido@wzv[3] sh -x sh
+ cat a
m=
guido@wzv[4] exit
Script done, file is typescript

And on FreeBSD, we see:
Script started, file is typescript
guido@gvr[101] cat a






guido@gvr[102] cat sh
m=`cat a`
guido@gvr[103] sh -x sh
+ cat a
+ m=





guido@gvr[104]
Script done, file is typescript
