Reposting with a catchier subject since it would be nice to get more
testing for these changes.
If you want to see boring commentary of my most recent change, you can
check out:
http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/cygwin/DevNotes.diff?r1=1.3&r2=1.4&cvsroot=src
This file is mainly there to help organize my thoughts when making a
change and to help my future self when he tries to figure out why a
change was made. It may be mildly interesting for anyone who wonders
why a change was done a certain way.
If you have the time, I'd appreciate hearing if this snapshot works ok.
I'm particularly interested in hearing about a problem if 1) you have a
pathological case where something like "cmd /c start ..." still doesn't
work right or 2) there is a regression from 1.7.14.
Thanks.
