Linux - working with filenames and directories starting with a - (dash)

I use SVN daily on my Linux development server, but today I ran into a silly problem that took me some figuring out.

If you try to work with filenames that start with - (dash) such as "-filename.ext", you will get errors such as:

svn: invalid option character: i
Type 'svn help' for usage.

After some looking around, the solution for it was, instead of:

svn rm -filename.ext

To pass '--' as the first argument:

svn rm -- -filename.ext

Hope it helps anyone out there.
