The POSIX definition of line requires a newline at the end; if you have
text but no newline, the file is not a text file.  However, cat is not a
line-oriented utility, so it should not be caring whether the input
files are text based, and should not be injecting newlines into the
output if the input did not have newlines.

Please show us the content of the files you claim are being
mis-concatentated using something like 'od -tx1z', as well as the
contents of the output file, so that we can try to reproduce your issue.
