bug#40699: "dist Hook" documentation in manual is incorrect or unclear about write permissions

[Karl Berry]

Hi Vincent,

    So, if the subdirectories may not be writable, how can the rm in the
    first example work without changing the permissions first?

    [namely:]
    dist-hook:
            rm -rf `find $(distdir)/doc -type d -name .svn`

That example belongs to the preceding paragraph 
  (Occasionally it is useful to be able to change the distribution ...)
not the following paragraph that you quoted.

Also, not that I wrote any of this, but it seems to me that the
pervasive assumption is that the automake user in fact owns the file
trees in question. Thus rm -rf should work even if it's mode zero.
Of course it won't work on a read-only source tree, but, well, it's just
an example ... --thanks, karl.
