Package: xpdf
Version: 3.02-20
Severity: normal
Tags: patch
Because the "echo" and "read" commands interpret the backslash as a
special character, the xpdf wrapper doesn't correctly handle backslash
in file names after the -m option.
The attached patch correct this:
* many="$many\n$1" is replaced by many=$(printf "%s\n%s" "$many" "$1")
to add a real newline character.
* echo "$many" is replaced by printf "%s\n" "$many" to avoid backslash
being regarded as a special character.
* The -r read option (specified by POSIX) has been added for the same
purpose.
Note: a newline in a filename is not handled correctly, but to handle
it, one would need to output null byte terminated file names to a
temporary file and use xargs -0 -n 1 (unfortunately, neither bash
not dash can handle null bytes in parameters, that's why a temporary
file would be needed).
