createProcess implictlitly escapes and quotes command line parameters
I've just run into severe usability issue with the process library. It turns out that it performs quoting and escaping of command line parameters. The result is that it is impossible to run many shell commands that contain "unsafe" characters:
diff <(echo $ENV_FOO) <(echo $ENV_BAR)
awk 'NR<=10' Foo.txtbecause they are turned into some nonsense. The culprit is translate function in libraries/process/System/Process/Internal.hs. I'm not fixing this myself as I assume there was some motivation behind escaping and quoting. I'm assigning high priority as it makes impossible to create shell processes correctly.
