There is a prompt bug in bash that causes it to miscount the number of
displayed characters.  One workaround was to append '\[\]' to PS1.  Also,
a good habit to get into is to use single quotes in the shell when some
value contains backslashes.

However, I can't reproduce your problem on my system (I only see one '>'
with the above PS1 setting).  I don't believe you've posted the
information requested in the problem reporting guidelines at
<http://cygwin.com/problems.html> in this thread...  Please attach the
output of "cygcheck -svr" so that we can find out, among other things,
what version of bash you are using, as well as what else is different in
our setups.
