De-duplicate code and reduce the amount of code that has to be changed
when new BorderShapes are being added. This also adds and uses the
missing HasBottom().
When the chosen preview border shape has no left and/or right border,
the minimum total preview window size decreases. But due to the
hardcoded value for the minimum size of the preview window the size
could not be decreased further than 5.
The minimum window height decreases when no extra line for the
horizontal separator is used (e.g. with `--info=inline --no-separator`).
In this case the preview window should be able to occupy this extra
line.
Enable resizing the preview window by dragging its border with the
mouse. This works with all border styles except for `none`.
Counter-intuitively, having the border only on the opposite side of the
window works too - dragging from it will first decrease the preview size
to its minimum.
This command would cause a deadlock and make fzf crash:
fzf --bind 'start:reload:ls' --height ~100%
Because,
1. 'start' event is handled by Terminal
2. When 'reload' is bound to 'start', fzf avoids starting the initial reader
3. Terminal waits for the initial input to find the right height when
adaptive height is used
4. Because the initial reader is not started, Terminal never gets the
initial list
5. No chance to trigger 'start:reload', hence deadlock
This commit fixes the above problem by extracting the reload command
bound to 'start' event and starting the initial reader with that command
instead of letting Terminal start it.
This commit also makes the environment variables available to
$FZF_DEFAULT_COMMAND.
FZF_DEFAULT_COMMAND='echo $FZF_QUERY' fzf --query foo

This reverts commit dca2262fe6.
> For mouse support on mintty
> Fix#3847
The current implementation LightRenderer for Windows is unable to accept
non-ASCII input unlike the tcell renderer. So even though it supports
mouse on mintty, we shouldn't use it as the default.
* #3799
* #3847
When --sync is provided, fzf will not render the interface until the
initial filtering and associated actions (bound to any of 'start',
'load', or 'result') are complete.
