I'm using Cygwin bash prompt, and for long commands the text will wrap around on the same line as opposed to going to the next line despite setting my PS1 to simply ' $'.

I was already using MinTTY, and removing the newline in PS1 didn't help either. One piece of advice on this page did help. I executed this bash command:
kill -WINCH $$
In my case, running this once fixed the issue, even after logging out and back in. I'm not sure if this is always the case.
I had the same problem with MinTTY as well. The problem probably has something to do with the primary prompt (PS1).
The solution for me was removing the last 'new line' character from PS1 (right before the '$' sign):
user@host ~ $ echo $PS1 \[\e]0;\w\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n\$ user@host ~ $ export PS1='\[\e]0;\w\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\$ ' user@host ~ $
see http://cygwin.com/ml/cygwin/2001-07/msg00140.html for reference.
To make this change persistent, add export PS1='[\e]0;\w\a]\n[\e[32m]\u@\h [\e[33m]\w[\e[0m]\$ ' to your ~/.bashrc file.
@jtpereyda's answer is certainly on the mark. But for some reason I couldn't let this go, and dug a little deeper.
Expanding on this comment, if you resize the terminal while in vim (or any other full screen application that takes control of the tty away from the shell), the resulting
SIGWINCH is often not sent to the shell, so when it gets back control it doesn't know that the terminal has been resized.
When you resize your terminal it should call an
ioctl(..., TIOCSWINSZ, ...) on the master pty that vim is running in. This in turn results in a
killpg(SIGWINCH) on vim's process group.
The problem is that vim runs in its own process group distinct from the shell it was exec'd from, so the bash shell does not receive the
SIGWINCH and does not adjust its lines/columns appropriately.
If you want a permanent workaround, add
shopt -s checkwinsize to your
.bashrc. That makes bash check the window size (
ioctl(..., TIOCGWINSZ, ..)) after returning from each command, and update its lines/columns.
Something is broken in your terminal settings (probably).
I guess you would have already tried exiting that session and restarting a new one.
While you don't get a solution for the Cygwin terminal, give MinTTY a try (its actually better).
As commented by akatakritos, you probably resized your terminal while vim was open.
When this happens, just resize the terminal one more time and the issue goes away.
