Description

My test on groovy-1.0-beta-7:

// The output is not C:\test
println "C:
test"

// The output is not C:\ntest
println "C:
ntest"

// The output is not C:\rtest
println "C:
rtest"

// unterminated string literal
println "C:
"

// The output is C:\"
println "C:
""

And here is some similar issue from Jason Braucht:
-----------[Start of message]----------------------------
I think I'm seeing something similar using Groovy Version: 1.0-beta-7
JVM: 1.4.2_05-b04

'cmd /c dir /b /s \\myProjectName\\trunk
*.java'.execute()
behaves differently from:
"cmd /c dir /b /s \\myProjectName\\trunk
*.java"'.execute()

Based on my limited understanding of groovy, I thought those two
statements would work the same, but they don't. In the process of
trying to figure out what I was doing wrong I compiled both versions
and ran the .class through Jad. I noticed an extra slash being
inserted before the "trunk" in second example. The output from Jad is
as follows:

InvokerHelper.invokeNoArgumentsMethod("cmd /c dir /b /s
\\myProjectName\\trunk
*.java", "execute");

and

InvokerHelper.invokeNoArgumentsMethod("cmd /c dir /b /s
\\myProjectName\\\trunk
*.java", "execute"); // notice the extra
slash before "trunk"

When I looked at the .class with a hex editor, I noticed there was a
tab character in place of the 't' in trunk in the second example, so I
think Jad is decompiling properly.

Interestingly, when I tried:

"cmd /c dir /b /s \\myProjectName\\\trunk
*.java"'.execute()

the output is the same in the second example above:

InvokerHelper.invokeNoArgumentsMethod("cmd /c dir /b /s
\\myProjectName\\\trunk
*.java", "execute");

Is this behavior expected?
