* Improve use of svn merge, by specifying the file to merge, rather than
chdiring to the srcdir (which wasn't right when merging in a subdir). Thanks Ethan.

-svn's merge command has three twisty little syntaxes, none
-very DWIM-ish. For merging one file, apparently it is helpful
-to specify that file itself. [This patch][] does that.
-
-[This patch]: http://ikidev.betacantrips.com/patches/merge.patch
-
-The bug that this fixes is hard to demonstrate without
-generating a lot of noise, but you can get the idea by
-finding a file that was committed in a subdirectory and
-merging a change with it.
-
- [apu]$ emacs one/test.mdwn
- [apu]$ svn add one/test.mdwn
- A one/test.mdwn
- [apu]$ svn commit -m "Another test case for merging."
- Adding one/test.mdwn
- Transmitting file data .
- Committed revision 42.
- [apu]$ emacs one/test.mdwn
- [apu]$ svn commit -m "Change."
- Sending one/test.mdwn
- Transmitting file data .
- Committed revision 43.
- svn merge -r38:39 ~/ikidevwc/patches/merge.patch
- [apu]$ svn merge -r42:43 one/test.mdwn
- svn: Cannot replace a directory from within
- [apu]$ svn merge -r42:43 ~/ikidevwc/one/test.mdwn
- svn: Cannot replace a directory from within`
-
-CGI.pm does a command much like the last one. However:
-
- [apu]$ svn merge -r43:42 ~/ikidevwc/one/test.mdwn
- svn: Cannot replace a directory from within
- [apu]$ svn merge -r43:42 ~/ikidevwc/one/test.mdwn ~/ikidevwc/one/test.mdwn
- U /home/glasserc/ikidevwc/one/test.mdwn
-
-In other words, merging works only when you specify
-the file, or, alternately:
-
- [apu]$ cd one
- [apu]$ svn merge -r42:43 ~/ikidevwc/one/test.mdwn
- G test.mdwn
-
-... if you're in the same directory as the file. Note that if
-a file called "test.mdwn" happens to be where you are, it'll get
-changed! I think this is what is meant in `svn help merge` when
-it says:
-
- If WCPATH is omitted, a default value of '.' is assumed, unless
- the sources have identical basenames that match a file within '.':
- in which case, the differences will be applied to that file.
-
-So, to conclude: when merging two revisions of a file, either specify
-the file, or be in the same directory as a file with the same name.
-This patch makes the former always happen, whereas previously the
-second would sometimes not happen. It also obviates the call to chdir.
