* fix(PVS/V009): start file with special comment
* fix(PVS/V501): identical sub-expressions for comparison
* fix(PVS/V560): part of conditional expression is always true/false
* fix(PVS/V593): review expression of type A = B < C

Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times
and makes it easier to visualise which dependencies are actually
required.
Work on https://github.com/neovim/neovim/issues/549, but doesn't close
it since this only works fully for .c files and not headers.
Problem: Bogus error when string used after :elseif.
Solution: Do not consider a double quote the start of a comment.
(closesvim/vim#11534)

Omit ends_excmd2(): the same as ends_excmd() in legacy Vim script.
Co-authored-by: Bram Moolenaar <Bram@vim.org>
`!did_throw` doesn't exactly imply `!current_exception`, as `did_throw = false`
is sometimes used to defer exception handling for later (without forgetting the
exception). E.g: uncaught exception handling in `do_cmdline()` may be deferred
to a different call (e.g: when `try_level > 0`).
In #7881, `current_exception = NULL` in `do_cmdline()` is used as an analogue of
`did_throw = false`, but also causes the pending exception to be lost, which
also leaks as `discard_exception()` wasn't used.
It may be possible to fix this by saving/restoring `current_exception`, but
handling all of `did_throw`'s edge cases seems messier. Maybe not worth
diverging over.
This fix also uncovers a `man_spec.lua` bug on Windows: exceptions are thrown
due to Windows missing `man`, but they're lost; skip these tests if `man` isn't
executable.
Problem: Vim9: 'cpo' can become empty.
Solution: Use empty_option instead of an empty string. Update quickfix
buffer after restoring 'cpo'. (closesvim/vim#7608)

Omit test as it is Vim9 script.
Problem: When a test fails it's often not easy to see what the call stack
is.
Solution: Add more entries from the call stack in the exception message.

Use docs from latest Vim.
Problem: Vim9: script reload test is disabled.
Solution: Compile a function in the context of the script where it was
defined. Set execution stack for compiled function. Add a test
that an error is reported for the right file/function.

Omit stack_top_is_ufunc(): only used by Vim9 script.
Problem: Execution stack is incomplete and inefficient.
Solution: Introduce a proper execution stack and use it instead of
sourcing_name/sourcing_lnum. Create a string only when used.

Omit test_debugger.vim: superseded by later patches.
Omit check_map_keycodes(): N/A.
Omit kword_test.c: N/A (converted to a unit test).
Problem: Ex command error cannot contain an argument.
Solution: Add ex_errmsg() and translate earlier. Use e_trailing_arg where
possible.

Add space around arithmetic operators '+' and '-'.
Remove space between back-to-back parentheses, i.e. ')(' vs. ') ('.
Remove space between '((' or '))' of control statements.
Add space between ')' and '{' of control statements.
Remove space between function name and '(' on function declaration.
Collapse empty blocks between '{' and '}'.
Remove newline at the end of the file.
Remove newline between 'enum' and '{'.
Remove newline between '}' and ')' in a function invocation.
Remove newline between '}' and 'while' of 'do' statement.
xstrnsave is a clone of vim_strnsave that uses char* instead of char_u*.
Its purpose short-term is to help reduce the number of casts and for
long-term to replace vim_strnsave as the need to use char_u is
eliminated.
Problem: Illegal memory access with invalid sequence of commands.
Solution: Do not call leave_block() when not in a try block. (closesvim/vim#8966)
Reset did_emsg so that exception is shown as an error.

Vim9script is N/A, which includes leave_block.
Problem: Still crash with error in :catch and also in :finally.
Solution: Only call finish_exception() once. (closesvim/vim#8954)

Exclude CSF_FUNC_DEF change (Vim9script).
