Make "sage -c 'attach(...); print 3'" work right

[jhpalmieri]

This was first reported on stackoverflow.

While running Sage:

sage: attach("file.sage"); print 3

works, but from the shell:

$ sage -c "attach('file.sage'); print 3"

fails. It actually tries to execute the command

sage "/path/to/'file.sage'; print Integer(2)"

and so it tries to read everything between the first and last quotes as the file name, thus producing the error

python: can't open file '/path/to/'file.sage'; print Integer(2)': [Errno 2] No such file or directory

This is because the script sage-eval tries to do something clever when the command to be executed starts with attach or load, but it is assuming that the rest of the command consists entirely of the file name.

Problem was introduced by #508.
Since I couldn't find an answer why ./sage -c "attach file.sage" was supposed to work, I suggest to revert the changes made in #508.

+1 to undo the "something clever"
