* doc/misc/efaq-w32.texi (Compiling, Debugging): Mention
MinGW64-w64/MSYS2 as the preferred way for building Emacs on
capable systems.
(Attachments with Gnus): Catch up with emacs-mime.texi in the
example given.
(Spell check): Add the availability of GNU Aspell and Hunspell
in MSYS2 distribution.
(Other useful ports): Add an entry for MinGW64-w64/MSYS2.
Fix link for MinGW homepage.
Remove entry for defunct UWIN project. (Bug#55930)
* test/src/process-tests.el (process-async-https-with-delay): Use
'plist-get' instead of 'assq' in testing for a connection error.
The 'status' variable is a plist, not an alist. (Bug#55849)
* lisp/progmodes/gdb-mi.el (gdb-breakpoints--add-breakpoint-row):
New function, extracted from 'gdb-breakpoints-list-handler-custom'.
Don't print "in <unknown>" for header-rows of breakpoints with
multiple locations that don't have a function name attached.
(gdb-breakpoints-list-handler-custom): Add to the breakpoint table
also any locations in multiple-location breakpoints, which are
supported since GDB 6.8.
* doc/lispref/strings.texi (Modifying Strings): Adjust to
implementation changes: it is possible for the modified string to
have fewer or more bytes than the original. Add recommendations
regarding unibyte vs multibyte strings and characters. (Bug#55801)
* doc/lispref/nonascii.texi (Converting Representations): Clarify
what 'string-to-unibyte' does. Reported by Richard Hansen
<rhansen@rhansen.org>. (Bug#55777)
* lisp/files.el (find-file):
(find-file-other-window):
(find-file-other-frame): Include the correct keymap so that
keystrokes are displayed better (bug#55761).
Copyright-paperwork-exempt: yes
* src/dispnew.c (adjust_frame_glyphs_for_frame_redisplay): Make
sure we have valid frame glyph matrices for the interactive
session. (Bug#55760)
(adjust_frame_glyphs): Add assertions for when we fail to allocate
valid frame glyph matrices for a TTY frame.
* lisp/net/tramp.el (tramp-restricted-shell-hosts-alist): Do not add
localhost when `tramp-encoding-shell' is a POSIX shell.
* test/lisp/net/tramp-tests.el (tramp-test31-interrupt-process):
Skip on MS Windows.
This fixes bug#55684. There, with a minibuffer-only frame at start up,
Emacs tried to switch to this frame, whose selected window was the
mini-window. There is no other active window in this frame, so the
attempt to swith to another window failed.
* src/frame.c (do_switch_frame): On switching to a frame whose selected
window is as above, before selecting the most recently used window, check
this ostensible window is an actual live window. Otherwise leave the
mini-window selected.
* admin/admin.el (manual-meta-string): Only include the first
line, and move the rest...
(manual-links-string): ...to this new string.
(manual-html-fix-headers): Don't remove the '<meta name=' elements
produced by makeinfo, especially not the 'name="viewport"' one,
which is essential for viewing the docs on mobile devices.

This fixes bug #55412. The call to Fselect_window was removed on 2021-03-21
in the commit "Prevent open minibuffers getting lost when their frame gets
deleted". This call is actually needed to determine current elements of the
pertinent window and frame when these are used in the frame title.
* src/frame.c (do_switch_frame): When the selected window in the target frame
is the mini-window, switch away from this window unless there is a valid
minibuffer there.
* src/frame.h (struct frame): Add an incidental comment about the element
selected_window.
* src/minibuf.c (move_minibuffers_onto_frame): No longer set the selected
window of the source frame. This action is now performed later, on returning
to that frame, in do_switch_frame when needed (see above).
* src/xdisp.c (gui_consider_frame_title): Replace the Fselect_window call and
associated ancillary settings.
