When responding to this i get
Forbidden
You don't have permission to access this resource.
Additionally, a 403 Forbidden error was encountered while trying to use an
ErrorDocument to handle the request.
I wanted to say what follows, but it is not that important anyway:
hvd@: if you want to have a quote mechanism, you should
open an issue. On the list kre@ has shown how a POSIX
shell can already today do that a couple of years ago:
<pre>
# Though slower use a subshell version instead of properly restoring $IFS
# and flags, as elder shells may not be able to properly restore flags via
# "set +o" as later standardized in POSIX, and it seems overkill to handle
# all possible forms of output "set +o" may or may not actually generate.
quote__rndtrip() (
case "$1" in
*\'*) ;;
*) printf "'%s'" "$1"; return 0;;
esac
a="$1" s= e=
while case "$a" in
\'*) a=${a#?}; s="${s}\\\\'";;
*\') a=${a%?}; e="${e}\\\\'";;
'') printf "${s}${e}"; exit 0;;
*) false;;
esac
do
continue
done
IFS=\'
set -f
set -- $a
r="${1}"
shift
for a
do
r="${r}'\\''${a}"
done
printf "${s}'%s'${e}" "${r}"
exit 0
)
quote_rndtrip() (
j=
for i
do
[ -n "$j" ] && printf ' '
j=' '
quote__rndtrip "$i"
done
)
quote_string() (
j=
for i
do
[ -n "$j" ] && printf '\\ '
j=' '
quote__rndtrip "$i"
done
)
</pre>
And Andrew Josey asked me in private whether there was
progress on that issue, and regarding dash in
particular i answered for one "Xu of dash for example
often is away for many months", and also "dash
explicitly goes for POSIX compliance, for example, and
the next release will ship with $'', interactivity for
stdin+stderr (not stdout), and more fixes / extensions
to *be* compliant", and i think it will be true here,
too.
