svn propedit (pedit, pe) — Edit the property of one or more items under version control. See svn propset (pset, ps) later in this chapter.
Edit one or more properties using your favorite editor. The first form
edits versioned properties in your working copy, and the second edits
unversioned remote properties on a repository revision
(TARGET determines only which repository to
access).

svn propedit对修改多个值的属性非常简单：
$ svn propedit svn:keywords foo.c
# svn will open in your favorite text editor a temporary file
# containing the current contents of the svn:keywords property. You
# can add multiple values to a property easily here by entering one
# value per line. When you save the temporary file and exit,
# Subversion will re-read the temporary file and use its updated
# contents as the new value of the property.
Set new value for property 'svn:keywords' on 'foo.c'
