I've found the answer to the question below, but I'm not sure that I
understand. I've used the same editor for all my Python coding for
awhile now. It is nice and clean, keeping to indentation standards,
etc. I turned on invisible characters and there is a linefeed after
every line.
However, if I pass the script through another editor and save it, I
don't get this error about a missing line feed.
I'm not sure what is going on. I got the missing linefeed error when I
dropped the WIKI code directly into the editor and saved it.

I wanted to see how it would be to port one of the bash scripts to
Python. I followed the WIKI template and it didn't run. So I made a
script that is ONLY from the WIKI template and it doesn't run
either. I've tried it by just typing the script into the command
prompt and also by typing:
python $GISBASE/scripts/pytest.py
The error is the same every time and is rather strange:
Line too long or missing newline at line 75
Line 75 is the last line (blank) of the script. If I get rid of this
line, I still get the error, but on line 74.
I'll paste in the WIKI script below so you won't have to look it up.
It seems OK and the error is kind of enigmatic. I've tried various
permutations and get the same results.
