Instead of checking whether this file exists in `diff_base` and
returning early, we let `git show` fail, which still creates an empty
`from_file` for the subsequent `git diff` to use.
This mostly reverts 2ee95686c5, but we
keep the test case.
Previously the mapping was set in the original window not the floating
window, so <Esc> in the floating window did nothing (when it should have
closed it) while <Esc> in the original window closed the floating window
(when it should have done nothing).
Fixes#868.
If fileformat is dos and eol is not set, then a '\r' (but without '\n')
will be written to the last line of temporary buffer file, which will
confuse git and make git think all lines are modified. Fix it by adding
'r' to all lines except the last one if fileformat is dos and eol is not
set.

If a file is subject to a clean/smudge filter, it is impossible to stage
an individual hunk. Therefore if the user tries to stage a hunk, ask
whether they want to stage the entire instead.
Determining whether a clean/smudge filter applies is done with:
git check-attr filter -- path/to/file
– and looking for "unspecified" (not to be) in the output. The result
is cached so that for a file which is not filtered (the common case),
staging multiple hunks only incurs the cost of the external call once.
See #796.
This tells git-show to output the smudged version of a file if a
clean/smudge filter is defined for it. In turns this allows us to diff
the buffer contents (which is smudged) against the reference version.
However patches cannot be applied.
See the man pages for git-show and gitattributes for more information.
See #796, #435.
If g:gitgutter_diff_base has been set and the file being processed does
not exist in that branch/commit, ensure that every line is marked as
added - this is how git-diff behaves.
Fixes#855.
E.g., passing an empty group name to the sign argument linehl (e.g.,
"linehl=") causes the following error:
```
Error detected while processing /usr/home/0mp/.vim/plugged/vim-gitgutter/plugin/gitgutter.vim[96]..function gitgutter#highlight#define_signs[10]..<SNR>56_define_sign_line_highlights:
line 9:
E1249: Group name missing for linehl
```
This patch makes the those errors go away by passing "None" when no
group name is needed.
This only applies to floating preview windows on Neovim.
Handles the following way of closing the floating preview:
- <Esc>
- Moving cursor
- 2<C-W>c (where 2 is the floating window's window number)
- <C-W><C-W> to move into and out of the floating window
Closes#786.
