No, modern Windows versions (beyond Windows 9x) support up to 32KB
long command lines.

However, users may have Grep installed, but not Findutils.  Especially
since the Findutils port from the popular GnuWin32 collection is very
buggy (`locate' simply doesn't work, `xargs' dies with mysterious
error message, and `find' is abysmally slow).  I had to roll my own
port to be able to use the package.

So I think on Windows it might make sense to use recursive Grep by
default.
