Problem: The maximum search count uses a hard-coded value of 99
(Andres Monge, Joschua Kesper)
Solution: Make it configurable using the 'maxsearchcount' option.

Problem: regexp: max \U and \%U value is limited by INT_MAX but gives a
confusing error message (related: v8.1.0985).
Solution: give a better error message when the value reaches INT_MAX
When searching Vim allows to get up to 8 hex characters using the /\V
and /\%V regex atoms. However, when using "/\UFFFFFFFF" the code point is
already above what an integer variable can hold, which is 2,147,483,647.
Since patch v8.1.0985, Vim already limited the max codepoint to INT_MAX
(otherwise it caused a crash in the nfa regex engine), but instead of
error'ing out it silently fell back to parse the number as a backslash
value and not as a codepoint value and as such this "/[\UFFFFFFFF]" will
happily find a "\" or an literal "F". And this "/[\d127-\UFFFFFFFF]"
will error out as "reverse range in character class).
Interestingly, the max Unicode codepoint value is U+10FFFF which still
fits into an ordinary integer value, which means, that we don't even
need to parse 8 hex characters, but 6 should have been enough.
However, let's not limit Vim to search for only max 6 hex characters
(which would be a backward incompatible change), but instead allow all 8
characters and only if the codepoint reaches INT_MAX, give a more
precise error message (about what the max unicode codepoint value is).
This allows to search for "[\U7FFFFFFE]" (will likely return "E486
Pattern not found") and "[/\U7FFFFFF]" now errors "E1517: Value too
large, max Unicode codepoint is U+10FFFF".
While this change is straight forward on architectures where long is 8
bytes, this is not so simple on Windows or 32bit architectures where long
is 4 bytes (and therefore the test fails there). To account for that,
let's make use of the vimlong_T number type and make a few corresponding
changes in the regex engine code and cast the value to the expected data
type. This however may not work correctly on systems that doesn't have
the long long datatype (e.g. OpenVMS) and probably the test will fail
there.

Problem: fuzzy-matching does not prefer full match
(Maxim Kim)
Solution: add additional score for a full match

fixes: vim/vim#15654closes: vim/vim#163005a04999a74
Problem: no fuzzy-matching support for insert-completion
Solution: enable insert-mode completion with fuzzy-matching
using :set completopt+=fuzzy (glepnir).

matchparen: do not use hard-coded match id (vim/vim#13393)
* matchparen: do not use hard-coded match id
Instead of using the hard-coded match id 3, which may also be used by
other plugins, let the matchparen plugin use whatever ids are
automatically returned when calling matchaddpos().
For backwards-compatibility, keep the `:3match` call, which will still
use the hard-coded id 3 (as mentioned in :h :3match).

Problem: A pattern that matches the cursor position is bit complicated.
Solution: Use a dot to indicate the cursor line and column. (Christian

Also use `n = ++vcol` in regexp_bt.c as `++vcol` alone fails lint.
Problem: Cannot see current match position.
Solution: Show "3/44" when using the "n" command and "S" is not in
'shortmess'. (Christian Brabandt, closesvim/vim#4317)

Problem: Character classes are not well tested. They can differ between
platforms.
Solution: Add tests. In the documentation make clear which classes depend
on what library function. Only use :cntrl: and :graph: for ASCII.

Update the documentation.
