I believe the bash-completion package is installed. It includes
/etc/bash_completion.d/p4 which is causing your problems. The version of
bash-completion included with 1.5 was not enabled by default, but the
current version is. This is why the problem surfaced with 1.7. (Note
that it has nothing to do with the Cygwin version but the version of
bash-completion instead.)

You can uninstall the bash-completion package if you don't want it at
all (which is probably true since you hadn't enabled it in 1.5) or
remove the /etc/bash_completion.d/p4 file.

(Personally, I created a /etc/bash_completion.d/disabled directory and
moved the files I didn't want there, for performance. I suspect I'll
have to manually repeat this every time I update bash-completion. There
may be a better "official" way to disable parts of bash-completion.)
