I believe that you will find that the file
tags/find_which_display.html has a newline
at it's end. If you don't have the *nix utility od, you can, with any
conventint
python, do:
f=open('path_to_tags_template_dir/tags/find_which_display.html', 'rb')
s=f.read()
f.close()
print repr(s)
Probably you have an editor that insists on ending files with
newlines. Or perhaps
you had not considered that newline. Anyway, I dummied up a test
version of your
code, and it works fine for me, with no trailing newline.
