Subject: [ruby-core:35229] [Ruby 1.9-Bug#4396] windows commands starting with "@" should run at all even though command string is quoted by `"'.

Issue #4396 has been updated by Jon Forums.


fwiw, behavior on win7 32-bit with lua v5.1.4 and python v2.7.1...

C:\>lua -e "os.execute('@echo foo')"
foo

C:\>lua -e "os.execute('^@echo foo')"
'@echo' is not recognized as an internal or external command,
operable program or batch file.


C:\>python -c "import os;os.system('@echo foo')"
foo

C:\>python -c "import os;os.system('^@echo foo')"
'@echo' is not recognized as an internal or external command,
operable program or batch file.
