On Windows, `mch_open_rw` is not actually doing what it claims. This
manifests as "E301: Oops, lost the swap file !!!" when filename is
changed with :file {name}.
Steps to reproduce (covered by test/functional/ex_cmds/file_spec.lua):
nvim -u NONE
:edit test
:file test2
E301 Oops, lost the swap file!!!
From libuv/src/win/fs.c:
void fs__open(uv_fs_t* req) {
...
attributes |= FILE_ATTRIBUTE_NORMAL;
if (flags & _O_CREAT) {
if (!((req->fs.info.mode & ~current_umask) & _S_IWRITE)) {
attributes |= FILE_ATTRIBUTE_READONLY;
}
}
Problem: Toupper and tolower don't work properly for Turkish when 'casemap'
is empty. (Bjorn Linse)
Solution: Check the 'casemap' options when deciding how to upper/lower case.

Problem: Toupper and tolower don't work properly for Turkish when 'casemap'
contains "keepascii". (Bjorn Linse)
Solution: When 'casemap' contains "keepascii" use ASCII toupper/tolower.

Problem: When making a character lower case with tolower() changes the byte
cound, it is not made lower case.
Solution: Add strlow_save(). (Dominique Pelle, closesvim/vim#1406)
cc5b22b3bf
Join almost identical strup_save and strlow_save functions to one
Function.
Before this commit it emitted e_spell_trunc in the first case and
treated file as completely valid on the second. While first is fine
(both errors are actually valid, though old error is probably better),
second results in incorrect regex used.
Problem: Possible overflow with spell file where the tree length is
corrupted.
Solution: Check for an invalid length (suggested by shqking)

CVE-2017-5953
A recent refactor left cpy without a NUL terminator, simplify the code
instead of patching over it.
Instead of plain memcpy, it'd be better to employ harder to misuse string
functions made for this purpose like xstrlcpy(), but path_tail() takes
char_u arguments and returns them, leading to a lot of ugly casting.
Fixes#6431.
