[Bug libc/5903] New: "iconv" creates unnecessary output

["titcouille dot mandriva at gmail dot com" <sourceware-bugzilla at sourceware dot org>]

This bug concerns the "iconv" utility. It's not really a bug, but bad design. I did:

iconv --from-code==LATIN1 --to-code=UTF-8 --output=file_to_convert.xml
output_file.xml

where mistakingly I had put my original file, file_to_convert.xml, as output
file. And for source file I had specified mistakingly some output filename which
doesn't exist. So iconv displayed that "output_file.xml" doesn't exist, that it
can't read from it, but replaced my original file (file_to_convert.xml) with an
empty 0-byte file. But it's stupid that it would put an empty file (and thus
destroy all my data) when there was nothing to convert in the first place.

To sum it up, don't create an output file when there isn't an input file.
