Add an entry to replace to lookout for paths that begin with "-"

[dfc]

When I was looking at the replace config for another bug I realized that there was no entry for '^-'. In light of the other defaults and the subsequent explanations it seems that looking out for pathnames that begin with a dash is a good candidate for inclusion. I looked and I did not find anything in my modest music collection but it does not mean its impossible.

Nobody likes this:

dfc@ronin:/tmp/BeetsIsAwesome$ ls -l
total 8
drwxr-xr-x 2 dfc dfc 4096 Feb 17 22:35 Artist One
drwxr-xr-x 2 dfc dfc 4096 Feb 17 22:36 -Artist Two
dfc@ronin:/tmp/BeetsIsAwesome$ cd -Artist\ Two/
-bash: cd: -A: invalid option
cd: usage: cd [-L|[-P [-e]]] [dir]
dfc@ronin:/tmp/BeetsIsAwesome$

I realize that there are ways around this (cd -- -ArtistTwo) but it is minor inconvenience / interruption in normal command line work flow. The default replace setting just needs an additional line;

'^-': _

Seems like a great idea to me. Can I convince you to do a pull request with:

• that proposed one-line change
• a changelog entry
• updated docs to reflect the new defaults

? Thanks!

Certainly. I was going to but I thought it would be more of a hassle for you. I just need to pull the latest beets changes.
