Re: Missing changes in merges from emacs-25 to master

[Paul Eggert <eggert@cs.ucla.edu>]

As near as I can make out, the changes in this commit:

commit aa636c8465b03c09249dccd68fca3d1df04eaa2c
Author: Eli Zaretskii <eliz@gnu.org>
Date:   Fri Jan 15 17:07:38 2016 +0200

     Fix crashes when mini-window has non-zero margins


were first lost in this merge commit:

commit 7823745acbe9b87eea2db4ef434e379fc903ec35
Merge: 6acd2aa bb0cd31
Author: John Wiegley <johnw@newartisans.com>
Date:   Mon Jan 18 22:56:33 2016 -0800

     ; Merge from origin/emacs-25

     The following commit was skipped:

     bb0cd31 Merge branch 'emacs-25' of git.sv.gnu.org:/srv/git/emacs into emacs-25


This merge commit skips a merge, which I think causes this particular problem. 
This merge commit is a parent of:

commit b895c72059521fec064ff27b4cfcfa4104081c4e
Merge: badcd38 1b76d91
Author: Vincent Belaïche <vincentb1@users.sourceforge.net>
Date:   Wed Jan 20 08:30:51 2016 +0100

     Merge branch 'master' of git.sv.gnu.org:/srv/git/emacs

which leads via a long thin graph to the merge commit 
82b089783e71b2aeef950eaecfe4cbc0735e64a2 that you identified as losing the 
change. One of the entries in that graph is this commit:

commit 64a568d6100e5eab5b86e8bd31846212654d1fcf
Author: Eli Zaretskii <eliz@gnu.org>
Date:   Wed Jan 20 11:47:19 2016 +0200

     Fix MS-Windows build broken by a botched merge from emacs-25

     * src/w32.c (w32_crypto_hprov): New static variable.
     (globals_of_w32): Initialize w32_crypto_hprov.
     (w32_init_crypt_random, w32_init_random): New functions.
     Include wincrypt.h.
     * src/w32.h (w32_init_random): Add prototype.


which indicates that Eli noticed a problem around then.
