Ok, I see now. From autofs(5):

If the filesystem to be mounted begins with a / (such as local /dev
entries or smbfs shares) a : needs to be prefixed (e.g.  :/dev/sda1).

...I guess it's necessary for the autofs parser. I assume that the ':'
doesn't get passed to the actual mount invocation though, so that
should continue to work just fine.

Well, better confusion now than confusion when it breaks. cifs really
is just too "loose" about the syntax of things that it accepts, which
sounds great until you have to test all of the different variations...
