Subject: [PATCH] Split up potentially long echo invocation on win32

Eggs with a very long infostr may trigger the maximum command line
invocation length of 8191 chars. To avoid running into this
limitation, the generated install script now creates an empty file,
then echoes each line into it.

Closes #1800
