I was just experimenting with a PowerShell v2 session (instead of the
basic Command Prompt) and got the following:
PS C:\_Projects> svn diff -r {2010-11-22}:HEAD
svn: Syntax error in revision argument '-encodedCommand'
If the revision range is enclosed in quotes, it works properly:
PS C:\_Projects> svn diff -r "{2010-11-22}:HEAD"
You can also escape the curly braces with the backtick character.
PS C:\_Projects> svn diff -r `{2010-11-22`}:HEAD
I believe the issue is specifically with the curly braces {}, as those
denote a code block in PowerShell.
Using a revision range of 3000:HEAD does not require that the range be
enclosed in quotes, but I'm going to try to get in the habit of just
quoting the revision range regardless.
Command Prompt works either way - quoted or unquoted, doesn't matter.
I'm on XP, it's probably an issue on newer versions of Windows as
well. Not sure how many folks out there are actually using svn.exe on
Windows in PowerShell, but it's in the list archive now in case anyone
has a similar issue.
