Is the behavior you are complaining about unique to Cygwin, or can it be 
reproduced on a GNU/Linux box?  If the latter, then an upstream bug 
report is better than asking for a cygwin-specific patch.  [Hint - as 
the maintainer of the cygwin bash port, I don't recall adding any 
cygwin-specific tweaks for mapfile - and a quick test on Fedora shows 
the same behaviors]
