Unable to scroll with mouse with #stop

[xudongzheng]

If LESSKEYIN file has #stop, then there is currently no way to scroll with the mouse. To reproduce:

seq 100 > example
echo "#stop" > lesskeyin
LESSKEYIN=lesskeyin less --mouse example

Additionally, it doesn't seem like the mouse escape keys from https://github.com/gwsw/less/blob/03f9f1a63ccf6ee32cee40640eb23d53ef88b850/decode.c#L75-L76

are defined in

https://github.com/gwsw/less/blob/03f9f1a63ccf6ee32cee40640eb23d53ef88b850/lesskey_parse.c#L32
