>Description:
When attempting to install pkgsrc via bootstrap on Cygwin, the bootstrap 
process fails with the log pasted below. The bootstrap failure only occurs if 
there is a space in the user's group-name (Called "Domain Users") in this 
example. It causes a 'sed' expression to terminate prematurely.

Stop.

*** Error code 1

>How-To-Repeat:
Perform a bootstrap under Cygwin (and possibly under other systems as well) 
with a space in the user's group name.
