While in the `while` loop at line 603 of function searchit(), memory
address ptr+matchpos is always valid. The strlen() check should not be
necessary to verify this.
Also added a check to prevent reading a line after the end of the
buffer.
An extra test in commit 0a116c828d was
introduced, to check for end of string with a call to strlen(). This was
necessary, because an incorrect length for invalid byte sequences was
used to step through the string. This slowed down find_match_text()
compared to vim's version.
To speed up things, the extra check was removed and a sequence length
of 1 for invalid byte sequences is used.
Fixes issue #3486
Problem: In a string "\U" only takes 4 digits, while after CTRL-V U eight
digits can be used.
Solution: Make "\U" also take eight digits. (Christian Brabandt)

Problem: Searching for a character matches an illegal byte and causes
invalid memory access. (Dominique Pelle)
Solution: Do not match an invalid byte when search for a character in a
string. Fix equivalence classes using negative numbers, which
result in illegal bytes.

Problem: When there are illegal utf-8 characters the old regexp engine may
go past the end of a string.
Solution: Only advance to the end of the string. (Dominique Pelle)

Problem: Autocommands triggered by quickfix cannot get the current title
value.
Solution: Set w:quickfix_title earlier. (Yannick)
Also move the check for a title into the function.

Problem: glob() and globpath() cannot include links to non-existing files.
(Charles Campbell)
Solution: Add an argument to include all links with glob(). (James McCoy)
Also for globpath().

Using `:cscope find s <cword>` with the cursor on a very short word like
`key` does not output the first line on the screen correctly: Output is
`Cscope tag: keyrd>` instead of
`Cscope tag: key`.
To fix this, clear the screen line after the first line was printed.
Variable tbuf going out of scope leaks the storage it points to.
We don't have to use the copy tbuf of a match. Because matches are always in
ctags style, we can operate on them directly.
Dereferencing a pointer that might be null(ptag) when calling strlen().
False positive. A match always contains a tab, so ptag is never null.
Because matches are always in ctags style, we can rewrite the code to
not use strtok().
Problem: 'foldcolumn' may be set such that it fills the whole window, not
leaving space for text.
Solution: Reduce the foldcolumn width when there is not sufficient room.

Unix systems must have this header but Windows does not have it at all.
Since src/nvim/os/unix_defs.h includes <unistd.h> without the guard
in order to avoid including this in the numerous places we would
need <unistd.h> on Unix we just include src/nvim/os/os.h which will pull
in <unistd.h> for us.
