shell_env fails when using csh

[dgloe]

On Fabric 1.8.0 and python 2.7.9 shell_env fails with csh since it tries to use export instead of setenv.

dgloe@flubber-elogin1:~> cat fabrictest.py
import fabric.api

fabric.api.env.shell = '/usr/bin/csh -c'
fabric.api.env.host_string = 'localhost'

with fabric.api.shell_env(TEST='asdf'):
    fabric.api.run('echo $TEST')
dgloe@flubber-elogin1:~> python fabrictest.py
[localhost] run: echo $TEST
[localhost] Login password for 'dgloe':
[localhost] out: export: Command not found.
[localhost] out:


Fatal error: run() received nonzero return code 1 while executing!

Requested: echo $TEST
Executed: /usr/bin/csh -c "export TEST=\"asdf\" && echo \$TEST"

Aborting.

I had similar problems and found a fix: You need to set backslash_quote in csh. See pull request #1483 . env.shell still needs to point to a working bash or sh. Feedback welcome.

Thanks @mradziej - rolling into the doc change in #1483.
