svn scripts cannot handle files with @ symbols

[Stephanie Lewis]

svn scripts cannot handle files with @'s symbols.  In svn @ means look at this file at a specific revision.  We should escape them by adding a second @ at the end.  This causes svn to ignore the first.

Please add a helper function to VCSUtils.pm that escapes a path and call that from the places that need it rather than duplicating the logic across all of these scripts.

Since this function only makes sense for Subversion, it should probably either do nothing for git or have a name that makes it clear it's Subversion-only. Maybe escapeSubversionPath?

You can do this more succinctly with map:

my @escapedPaths = map(escapePath, @paths);

Seems like $pathsString should become a variable that's only used in the git codepath.

Same comments as above.

You should use $escapedPath in the error message too.
