Subject: [PATCH] iniWriteFile(): don't truncate the file to 0-bytes before
 writing the contents, instead truncate to the new length after writing the
 contents. This should make .ini files more tolerate of "out of disk space"
 situations and reduce the risk of lost data (0-byte .ini files) due to low/no
 disk space.
