Please test the following:

does that change anything?

This bug has bothered me for years, I would love to see it fixed. Here is a
simple test case:
$ cat ~/.bash_history
echo ABCDEF ABCDEF ABCDEF ABCDEF
echo 0123456789 0123456789 0123456789 0123456789 0123456789 0123456789
Result:
$ echo ABCDEF ABCDEF ABCDEF ABCDEF 234
What I tried:
1. PS1=%
2. "TERM" with no "am" or "bw"
3. "TERM" with both "am" and "bw"
4. "TERM" with "am" only (couldnt find one with "bw" only)
If you have a custom terminal that this works with - provide the "infocmp"
output and I will try it. Note that I am not using Mintty, I am just using
sh.exe and conhost.exe, so it seems that mintty is not the culprit but perhaps
Cygwin DLL or Readline.
