Subject: [PATCH] Bug 707510 - don't use strlen on passwords
Item #1 of the report. This looks like an oversight when first coding
the routine. We should use the PostScript string length, because
PostScript strings may not be NULL terminated (and as here may contain
internal NULL characters).
Fix the R6 handler which has the same problem too.
