[PATCH] Re: propedit on svn:mime-type

Been a bit busy with other stuff, so it took longer than I expected,
but here's the patch. It passes make check now.

Alex

* subversion/libsvn_wc/props.c
  (svn_wc_prop_set): Force svn:executable to a specific value, Strip all
  leading and trailing whitespace for svn:mime-type, svn:eol-style and
  svn:keywords. Make sure that the last line in the prop value ends in a
  newline for svn:ignore and svn:externals.

* subversion/include/svn_props.h
  (SVN_PROP_EXECUTABLE_VALUE): New value to force svn:executable to.

* subversion/tests/clients/cmdline/prop_tests.py
  (copy_should_use_copied_executable_and_mime_type_values): Take account of
  svn:executable being forced to "*".
  (strip_or_add_whitespace): New test for whitespace stripping.

* subversion/tests/clients/cmdline/schedule_tests.py
  (add_executable): Take account of svn:executable being forced to "*".

* doc/book/book/ch06.xml: Mention new behaviour of svn:executable.
