spsl SENDLINE does not work in mintty

[redlegoman]

SuperPutty 1.4.0.9.

When using SPSL with a mintty session, SENDKEY {ENTER} does not work and SENDLINE does not send a carriage return. So for example the SPSL command: SENDLINE echo "hello" results in this

$ echo "hello" with the cursor waiting at the end of the line. If I press enter myself, the command executes.

If I put two SENDLINEs together like so:

SENDLINE echo "hello"
SENDLINE echo "world"

I end up with $ echo "hello"echo "world"
