So far, Org used either `fit-window-to-buffer' or
`shrink-window-if-larger-than-buffer' without any further checks when
displaying one of its many help and selection buffers. This can cause
problems if the user has set up Emacs to split windows horizontally
rather than vertically, because the window being shrunken then may be
side-by-side with another window, and shrinking the height of one will
also change the other.
With this patch, shrinking a window always goes through the new
function `org-fit-window-to-buffer' which only acts if the current
window spans the whole width of the frame.
Furthermore, this function also helps with compatibility, because it
falls back to `shrink-window-if-larger-than-buffer' if
`fit-window-to-buffer' does not exist, as is the case on older version
of Emacs and XEmacs.
When marking a repeated entry DONE in the daily or weekly agenda, that
task would previously still be shown as TODO, because the repeater
immediately restores the TODO state after moving the time stamp. This
is bad feedback.
This problem was hard to fix. Because the same line may be present in
other lines in the same weekly agenda, we cannot simply update all
lines related to this entry.
What we do now is this: Before the repeater does its work in shifting
the time stamp and resetting the TODO keyword, we take a snapshot of
the headline as it looks then. And then, when we update the agenda
view, we change only the line at the cursor instead of all lines
related to this entry. We also make sure that this is only so if the
cursor is in a daily/weekly agenda, on TODAY's date.
There still remain possible inconsistencies. For example, if you have
a daily repeating task in the weekly agenda, and you move the cursor a
few days into the future and mark it DONE there, the entry will
actually be marked DONE for today, but still show up in today's task
list as TODO. refreshing the agenda will fix the display in such an
unlikely case.
Thanks to Jack ??? for noticing and reporting this issue.
C-c C-c still works with the cursor in a headline,
but I wanted a special binding as the default, mainly
in order to be able to set tags in a remember buffer.
The new default asks to open all those files in Emacs, for which
`auto-mode-alist' does contain an entry. The reasoning is that
Org-mode users are Emacs users and probably like to use exactly
this setup. The only exception configured as such by default is
that files with html or xhtml extensions will be opened using
the system default, most likely a browser.
