hi,
  Hard as it is for me to believe, it seems I have uncovered a bug in the paste command. I got unexpected/incorrect results in the course of my work (which I can describe as merging two data files from some electronic test equipment for the purposes of analysis and plotting). Attached is a tarfile of a test case with two files and a log showing the incorrect results and the version info of paste.
   I hope this email will reach the right people to investigate this.
    If it is a known issue and there is a workaround for me to use, please do let me know.
  Thanks, sincerely,

      Gerard Visser

It is only your terminal emulator that tricks you: Your file contains
carriage returns that moves cursor to the first column, so that next
line will appear on top of the previous.

$ file e f
e: ASCII text, with CRLF line terminators
f: ASCII text, with CRLF line terminators

If you do `paste e f | cat -A`, you can see it yourself what's going on.
Use `tr -d '\r'` to remove unwanted CRs.

Hello,
My apologies for the false bug report, you are quite right and I should have thought of this possibility. Burned again by naively taking files from Windows systems. Oh well.
Thank you for taking the time to point this out, I will be more careful in future. Please close the case.
Sincerely,

      Gerard
