The TortoiseSVN description seems a bit out-of-date; going off the wiki's
instructions, I had to trial-and-error a few options before I got it right.
(It doesn't help that all operations seem really really slow...not sure if
this is an SVN problem or internet connection problem...)

For one thing, it seems that the semantics of the "From URL" and "To URL"
have changed, or were incorrect to begin with (the latter making more sense
to me). The present TortoiseSVN entry has release as From and trunk as To,
which seems backward to me and appeared backward from the present
TortoiseSVN interface.

Okay if I leave the present TortoiseSVN entry, marked for older versions,
and add another entry for TortoiseSVN 1.7.6+? Or maybe just scrap the old
TortoiseSVN entry and replace it?

 * TortoiseSVN:
   * Start with a working copy of
https://svn.boost.org/svn/boost/branches/release.
   * Select the directory and/or files to be merged.
   * Right-click selection for context menu, and "TortoiseSVN" > "Merge..."
   * For recent versions of TortoiseSVN (e.g., 1.7.6+)
     * Select "Merge a range of revisions"; click "Next >".
     * Populate "URL to merge from": https://svn.boost.org/svn/boost/trunk/.
..
     * Leave "Revision range to merge" empty to merge all revisions
(typical).
     * Click "Next >".
     * Click "Test merge" to be sure the setup is correct.
     * Click "Merge". (Note that this modifies your working copy, not the
repository.)
   * For older versions of TortoiseSVN
     * From: https://svn.boost.org/svn/boost/branches/release/...
     * To: '''Uncheck''' the Use "From:" URL checkbox.
     * To: https://svn.boost.org/svn/boost/trunk/...
     * To: Head revision
     * Click "Dry run" button to be sure setup is correct.
     * Click "Merge". (Note that this modifies your working copy, not the
repository.)
