* frame.c (x_set_frame_parameters): Always calculate new sizes
pixelwise to avoid potential loss when rounding.
* window.el (fit-frame-to-buffer): Get maximum width from
display's width instead of height.
* doc/emacs/misc.texi (Saving Emacs Sessions):
Be briefer about desktop's handling of frames.
The manual does not need to mention every option, nor should
it just repeat the doc-strings.

(desktop-restore-in-current-display, desktop-restore-forces-onscreen)
(desktop-restore-reuses-frames): Doc tweaks.

when the advice is pending.
(advice-remove): Remove this marker when not needed any more.
* lisp/desktop.el (desktop-restore-forces-onscreen)
(desktop-restore-reuses-frames): Use non-keyword values.
(desktop-restore-frameset): Use CLEANUP-FRAMES arg of frameset-restore.

(frameset--reuse-list): Remove definition; declare.
(frameset--action-map): Declare.
(frameset--find-frame-if): Doc fix.
(frameset--restore-frame): Cache frame action.
(frameset-restore): New keyword arg CLEANUP-FRAMES, allows to select
how to clean up the frame list after restoring. Remove cleaning
options from REUSE-FRAMES. Change all keyword values to symbols.
(frameset--jump-to-register): Simplify by using CLEANUP-FRAMES.
Do not add `nil' to the environment, when there's no remote `locale'.

installed perl, before sending scripts.
* window.c (Fother_window_for_scrolling): Check that
Vother_window_scroll_buffer is a buffer.
* window.el (fit-frame-to-buffer, fit-frame-to-buffer-margins):
Fix doc-strings.
(fit-frame-to-buffer): New argument ONLY. Remove dependency on
fit-frame-to-buffer variable. Fix doc-string.
(fit-window-to-buffer): Set ONLY argument in call of
fit-frame-to-buffer. Fix doc-string.
* frames.texi (Size and Position): Rewrite entries for
`fit-frame-to-buffer' and `fit-frame-to-buffer-margins'. Add
description for `fit-frame-to-buffer-sizes'.
* windows.texi (Resizing Windows): Add descriptions for
pixelwise resizing. Add entries for `window-resize-pixelwise'
and `fit-window-to-buffer-horizontally'. Rewrite
`fit-window-to-buffer' entry.
(tramp-action-password): Clear password cache if needed.
(tramp-read-passwd): Do not clear password cache.
* net/tramp-gvfs.el (tramp-gvfs-handler-askpassword): Clear password
cache unless it is the first password request.

doc-string.
* window.el (window-min-height, window-min-width): Rewrite
doc-strings.
(window-body-size): Add PIXELWISE argument to make it consistent
with its callees.
* display.texi (Window Dividers): New section.
* frames.texi (Layout Parameters): Add right-divider-width and
bottom-divider-width.

description. Rewrite descriptions of `window-total-height',
`window-total-width', `window-total-size', `window-body-height',
`window-body-width' and `window-size-fixed'. Add descriptions
for `window-pixel-height', `window-pixel-width',
`window-min-height' and `window-min-width'. Remove description
of `window-size-fixed-p' moving part of it to that of
`window-size-fixed'.
(Resizing Windows): Mention dividers when talking about minimum
sizes.
(electric-indent-mode): Fix accordingly.
* lisp/progmodes/cc-mode.el (c-initialize-cc-mode): Only hook into
electric-indent-mode-hook if we obey electric-indent-mode.
