True, update won't delete a user's current working directory.
So `svn update .` doesn't do any harm.
But most users in my community use GUIs like TortoiseSVN, which will
delete a directory whose branch has moved. So will `svn update
<subdirectory>`; for example:
$ ls d1
d0 d1 d2 f0 f1 f2
$ svn move -m "move d1" %REPO%/d1 %REPO%/b2/d1
Committed revision 19345.
$ cd d1
$ svn update .
svn: REPORT request failed on '/svn/etc./!svn/vcc/default'
svn:
Cannot replace a directory from within
$ cd ..
$ svn update d1
D d1
Updated to revision 19345.
$ ls d1
ls: d1: No such file or directory
