GCC 12.2 rightfully complains about an out-of-founds array access.
This can possibly happen for unsupported variable names.

This allows:
- to mimic native behavior when a stray '\0' is present in file
(in 'FOR /F' execution, it's interpreted as an EOF marker)
(prevents an infinite loop)
- supports (with /USEBACKQ) unicode output (if BOM is present)

There are cases where the read can fail (not attached to a console,

Found while trying to look into bug 44236.
A batch script is executed containing a line like this:
if (%1)==(p) start /W " " "%SFDIR%WSFplot" wr2300.t35 3
This returns an error like this:
Syntax error
Can't recognize 'p' as an internal or external command, or batch script.
It looks like native does handle the brackets differently when contained
inside the condition part of the if command.

With the 'for' loop /f syntax, if tokens are requested the the normal
syntax is something like tokens=1,2* but there is valid syntax like
1,2,* (which effectively means the same). Make this other syntax work.

Avoid whitespace affecting the parsing of a for loops items. The
leading and trailing quote or backtick needed removing, and it was
assumed that the trailing character would be that character, which was
wrong when there was whitespace unless the parameter is trimmed.

'if exists' takes a parameter which can be directory, directory\ or
directory\. for example, and should equate to true if the directory
exists. The syntax directory\ is explicitly rejected by FindFirstFile
and hence was not working - look for this specific case, and if found
append a '.'.

for /f can run a program and parse its output. The program name can
supply args and be quoted or not. If quoted, wine fails to run the
program because internally we were adding an extra pair of
quotes. These are not needed and can be removed.

A single line if statement causes problems when it has redirects
and/or continuation type operators (|, &&, || etc) because it is
expected that if there is more than one command in the 'if', then it
will use brackets. This patch changes the 'if' parsing to emulate
brackets at a continuation character. In addition, 'for' and 'if'
statements do not have their output redirected immediately, instead it
is redirected on the individual commands being executed not the
statement itself. We were opening the redirect once for the 'if' and
once for the processing of the statement inside the if.

When inside a for loop, an 'if' statement is processed and the true part
taken. Once all the commands in the true are processed, the else part is
parsed, and a flag set to skip all commands in the else part. Unfortunately
this flag is left on even when the if statement ends, meaning subsequent
commands are also skipped.

for /f allows a special syntax of tokens=* (rather than tokens=1* for example)
which just means put the whole line into the next variable). Note the handling of
the 'next variable' was wrong in the case of it being 'A' or 'a' as the wrap
calculation was wrong, but this only affected using this new syntax.

In an error condition, the wrong variable was being used for an insert,
resulting in a read from uninitialized data. This could be triggered for
example by 'ftype jason=', and the error message should have included
jason but instead was just ''.

A call or a goto will find the next matching label not the first one in the
file. This means it could be later in the file or it could be earlier in the
file, so make goto (which 'call' also uses) first scan from current file
position to the end of the file, and subsequently from the start of the file
to the wrap point.

A for loop can be working through a wildcarded subdirectory, but when
