yes-or-no-p prompt conditionally broken in master?

[Kaushal Modi]

Hi all,

I tend to keep my e

​​

macs build updated with the master every few days.

My last build was 2 days back at this commit: http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=a3c31adea4970b8a7fc7f495e6a6a6d4a93e69ce and everything worked fine.

PROBLEM:

- When on latest master, for ANY yes-or-no-p prompt, for the first prompt I cannot see the prompt question. At times, all I see is the cursor at the very left in the minibuffer. At times, I see no cursor and have to assume that the minibuffer is in focus. I blindly need to hit y or n to proceed (for example when quitting emacs). Some times, 2nd prompt onwards the prompt questions start appearing fine.

- This issue goes away if I revert to the above linked commit with my emacs config.

- This issue also goes away in an emacs -Q session while on the latest commit on master.

Below are all the commits after that commit that works for me.

So some package I have installed is clashing with one of the below commits.

I tried debugging but cannot narrow down to the problem. Can one of the authors would know if their commit could have possibly changed how yes-or-know-p prompt display behaved? A proper direction will help me debug the problem faster.

PS: One of the packages I have installed is http://elpa.gnu.org/packages/minibuffer-line.html and I thought that that might be causing the problem. But disabling that did not fix this.
