Docs: leading slash

[jehon]

Hello dear great developers of this great product!

In the "mount" manual page (here: https://rclone.org/commands/rclone_mount/), it didn't say that we can not use a leading slash.

So in systemd, the mount unit:

[Mount]
Type=rclone
What=cloud:Photos
Where=/mnt/cloud/photos

will work, while

[Mount]
Type=rclone
What=cloud:/Photos                   # Mind the / in /Photos
Where=/mnt/cloud/photos

Will not.

I took me 6 months to figure that out (yes, I am a bit stubborn) :-)

Could we implement the test somewhere? For example, in the PCloud helper? Or perhaps more globally?

Thanks in advance...
