...onvention; but it also broke support for releases that begin with 'R'. Removing this sed command fixes.

I'm not a sed master; but it looks like that command removes the R from the releases. .kerl/otp_releases file goes from looking like this

R10B-0
R10B-10
R10B-1a
...
17.0
17.0-rc1
17.0-rc2

To looking like this

10B-0
10B-10
10B-1a
...
17.0
17.0-rc1
17.0-rc2

kerl now wants you to do
> kerl build 10B-0 10b-0
...
> cat /home/burrows/.kerl/archives/otp_src_10B-0.tar.gz

Object Not Found

Object Not Found

The requested URL /download/otp_src_10B-0.tar.gz was not found on this server.

And if you do
> kerl build R10B-0 10b-0
R10B-0 is not a valid Erlang/OTP release

So I think the leading R must remain.
