[Rd] R -e "" crashes on Windows (but not Rterm -e "")

[Henrik Bengtsson]

On Windows, the following crashes "R for Windows terminal front-end":

R -e ""

whereas

Rterm -e "" or R -e " " (a space in the expression) doesn't.

I observe this on:

- R Under development (unstable) (2013-07-26 r63419) [Platform:
x86_64-w64-mingw32/x64 (64-bit)]
- R version 3.0.1 Patched (2013-07-25 r63414) [Platform:
x86_64-w64-mingw32/x64 (64-bit)]
- R version 3.0.1 (2013-05-16) [Platform: x86_64-w64-mingw32/x64 (64-bit)]
- R version 2.15.3 Patched (2013-03-13 r62402) [Platform:
x86_64-w64-mingw32/x64 (64-bit)]

Can others reproduce this?  If so, I'll submit a bug report.  (On
Linux/OSX it does not crash/core dump.).
