cli-repo-root-relative-support.txt update

Hi,

says:

ISSUE: zsh with 'setopt extendedglob' enabled
WORKAROUND: quote it in single quotes ('^')

I suggest the following alternative:

WORKAROUND: escape it with a backslash (\^) or quote it in single quotes ('^')

I prefer the backslash way as it needs one less character to type. :)
But on some keyboards, the single quotes may be easier to type.

Also, of course, zsh could be configured (from the .zshrc) to recognize
the use of ^/ with svn and do not treat ^ as a special character in
such a case. But I don't know how to do that.
