unknown operand in ash

Hi folks!

I wrote a small shell script for CGI Post Method handling and one part
of this script is this line:

[ "$REP" = "%" ] && REP="%%"

This works fine, as long as $REP is not "!".

[lxtc - ~ #] REP=%
[lxtc - ~ #] [ "$REP" = "%" ] && echo test
test
[lxtc - ~ #] REP=x
[lxtc - ~ #] [ "$REP" = "%" ] && echo test
[lxtc - ~ #] REP=!
[lxtc - ~ #] [ "$REP" = "%" ] && echo test
[: %: unknown operand
[lxtc - ~ #]

According to ash.c this happens because ash thinks that the leading
! has to be used as operand.

For the meantime, I helped my self out by modifying the line to the
following statement:

[ "x$REP" = "x%" ] && REP="%%"

I just wanted to point this out, maybe one of you with the specific
knowledge of ash.c can fix that.

ciao,
