git suddenly started putting up a dialog instead of asking for my password on the command line

[Joel Rees]

Git has suddenly started putting up a dialog box to ask for my
credentials instead of asking for my credentials at the command line.

I found the suggestion to set the following git configuration,

    git config --global credential.modalPrompt false

but it doesn't change anything.

Any suggestions what I might have installed, or what update might have
changed this behavior?
