 Because it removes *all* the properties, not only those that your
 application has set up.  This can be catastrophic for hooks that
 depend on properties being preserved.

 It is a much better coding practice to remove the properties you
 consider harmful (e.g. `read-only' or `keymap') using
 `remove-text-properties'.

 It may not be all that blasphemous for strings that you copy out of
a
 buffer.  Still, it's best avoided, unless you're sure you need it. 
Thanks for the explanation.

My basic problem is that I am copying strings from a buffer and
writing them out.  In some versions of emacs, this write text-property
crap into the output file.

Since I know what I want, and it is my code's file that I am removing
the properties from, I feel justified in using `set-text-properties'.

Again, thanks.
