Update of missing on non-working directory

[Vadym Chepkov]

Hi,

I think the exit code subversion returns isn't right, it should indicate an 
error

$ svn --version
svn, version 1.6.11 (r934486)


$ svn update /blah-blah
Skipped '/blah-blah'
$ echo $?
0

$ svn update /etc
Skipped '/etc'
$ echo $?
0
