sh question (Was: Re: modifying Anaconda)

[Simon Epsteyn]

I am going to ask a question about my own shell script.

I often see similiar test written as:

        if [ X"$1" != X"$2" ]; then

I would undersdant it if it was written as

        if [ X$1 != X$2 ]; then

but doesn't putting $1 and $2 in quotes make the X unneeded?  Are there any
bourne shells that break with simply

        if [ "$1" != "$2" ]; then

if one of the vars is empty?
