Well, the construct loops while there is a $ in "$tmpdir". It breaks
out of the loop when there isn't. That's quite straightforward. The
sed command replaces the three characters \ ` " with \ followed by the
characters. That gives an additional level of quoting which the eval
(which is there for expanding $ until none is left) then strips again.
It would be interesting to see what happens on the system where it
fails. One thing that might help is writing
's/[\\`"-"]/
instead, doubling the initial \ in case sed misinterprets the range (I
am not sure why we have "-" instead of just ", probably to stop syntax
highlighting from going complete bonkers).
Hi David:
Unfortunately, that doesn't help. And, I tried XPG4 sed and GNU sed
4.1.4. I also tried different CONFIG_SHELL settings: XPG4 Bourne,
zsh and bash. No matter what I do it inf. loops. Can someone send me
there Makefile? Maybe I can get an idea from that. Hopefully, from
some one who uses xemacs, but maybe that is not critical.
Thanks,
Rodney
