;;; Commentary:
;; This library implements the abstract major-mode `magit-mode' from
;; which almost all other Magit major-modes derive. The code in here
;; is mostly concerned with creating and refreshing Magit buffers.

an abbreviation of that.
`%x' If `magit-uniquify-buffer-names' is nil \"*\", otherwise the
empty string. Due to limitations of the `uniquify' package,
buffer names must end with the path.
`%T' Obsolete, use \"%t%x\" instead. Like \"%t\", but append an
asterisk if and only if `magit-uniquify-buffer-names' is nil.
The value should always contain \"%m\" or \"%M\", \"%v\" or

"Whether to keep the region overlay when there is a valid selection.
By default Magit removes the regular region overlay if, and only
if, that region constitutes a valid selection as understood by
Magit commands. Otherwise it does not remove that overlay, and
the region looks like it would in other buffers.
There are two types of such valid selections: hunk-internal
regions and regions that select two or more sibling sections.
In such cases Magit removes the region overlay and instead
highlights a slightly larger range. All text (for hunk-internal
regions) or the headings of all sections (for sibling selections)
that are inside that range (not just inside the region) are acted
on by commands such as the staging command. This buffer range
begins at the beginning of the line on which the region begins
and ends at the end of the line on which the region ends.
Because Magit acts on this larger range and not the region, it is
actually quite important to visualize that larger range. If we
don't do that, then one might think that these commands act on
the region instead. If you want to *also* visualize the region,
then set this option to t. But please note that when the region
does *not* constitute a valid selection, then the region is
*always* visualized as usual, and that it is usually under such
circumstances that you want to use a non-magit command to act on
the region.
Besides keeping the region overlay, setting this option to t also
causes all face properties, except for `:foreground', to be
ignored for the faces used to highlight headings of selected
sections. This avoids the worst conflicts that result from
displaying the region and the selection overlays at the same
time. We are not interested in dealing with other conflicts.
In fact we *already* provide a way to avoid all of these
conflicts: *not* changing the value of this option.
It should be clear by now that we consider it a mistake to set
this to display the region when the Magit selection is also
visualized, but since it has been requested a few times and
because it doesn't cost much to offer this option we do so.
However that might change. If the existence of this option
starts complicating other things, then it will be removed."
