The default values are 3 lines. With this change, scrolling speed now seems
similar to other programs like cmd.exe. Before this change it feels too slow.
I got to the bottom of the hang on startup when trying to connect
to the multiplexer on windows and it was because of the change
in 367a44fb96 to try to drain the pollable
channel.
This mapped to ReadFile on windows which always tries to fill the buffer
even if it is a socket under the covers.

teaches filedescriptor to use the recv/send if the filedescriptor is
really a socket and that resolves the hang.
Matching against the current dir when it includes a host and a
path seems like a handy way to automate selecting appropriate
theme/color/profile settings, so I'd like to make sure that
we have the full URL content available for that.

This mostly works, but has a cache invalidation issue wrt.
passing invalidated rows from the server to the client...
sometimes.
However, scrollback is cached on demand and selection works.
We need to build in release mode so targets are cacheable.
GH has a limit of 400MB per cache blob and we're at 750MB with
the debug build. Slim it down a bit.
The cache wants to hash the Cargo.lock file so I've removed that
from the ignore file and added it to the repo. This might cause
an error for users checking out the repo after this change is
pushed; removing the local Cargo.lock should resolve that.
