Commands with quotes fail to parse

[michalrus]

On 85d4008, e.g.:

$ echo "cabal test --test-options='1234'\\'' 567'"
cabal test --test-options='1234'\'' 567'

$ sos . -c "cabal test --test-options='1234'\\'' 567'"
sos: Error parsing command 'cabal test --test-options='1234'\'' 567''

@michalrus what's the use case here?

[michalrus]

@schell, say, if I wanted to match a Tasty test case with a space in name, I’d need that. The pure Cabal command would then be:

cabal test --test-options='-p '\''some test name w/ spaces'\'' --color=always'

Currently there’s no way to pass that command to sos -c [ … here … ].

[schell]

Yes, I see. The difficulty here is that within a command we use \ as the leader to a capture group. It's possible we simply need some logic around that to check for quotes, as that is obviously not a valid capture group.

I'll get this when I can but until then I welcome any pull request, @michalrus! Here's where the logic should probably go:
