commit 8ef3cff9d1ceafe369f982d980678d749fb93bd2
Author: Florian Weimer <fweimer@redhat.com>

    iconv: Support in-place conversions (bug 10460, bug 32033)

    Check if any of the input files overlaps with the output file, and use
    a temporary file in this case, so that the input is no clobbered
    before it is read.  This fixes bug 10460.  It allows to use iconv
    more easily as a functional replacement for GNU recode.

    The updated output buffer management truncates the output file
    if there is no input, fixing bug 32033.

iconv -o may produce executable files (depending on umask) because the mode is
incorrectly specified as 0777, not 0666.
