Normally I'd agree with this, but the help output for svn diff is,
uhhm, "substantial" is probably the best word. That doesn't matter on
my super-duper 500x80 terminal, of course, but not everyone is so
blessed :-) How about something to make the error message stand out
visually from the help, eg:
~/src/subversion> svn diff http://any.url/
---------------------------------------------------------
subversion/clients/cmdline/diff-cmd.c:92: (apr_err=205000)
svn: Client error in parsing arguments
svn: Second URL is required.
---------------------------------------------------------
diff (di): display the differences between two paths.
usage: 1. diff [-r N[:M]] [TARGET [TARGET ... ]]
Alternatively, we could output the usage message first, and then the
specific error message. On balance I think I'd prefer that.

I'm partial to purple, myself. With yellow polka dots. Goes with my
socks.
