Some buffers in WCMD_HandleTildeModifiers() are only of size MAX_PATH,
even though they handle strings that aren't necessarily
filenames. When changed to have size MAXSTRING, a stack overflow crash
with strings of size MAX_PATH stops happening.

Previously, invoking 'call' with an empty string would leave errorlevel
unchanged. Reset errorlevel to 0 to match the behavior of
the Windows 'cmd.exe'.

For example, the explicit path "C:\some;path" is currently treated as if
the PATH environment variable is "C:\some;path" which is obviously wrong,
and searches for the directories "C:\some" and "path".

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.

When processing a (..) multiline section, each line is processed and
if it starts with a '@' it is not echoed, but more importantly if is
'rem' then anything else on that line should be ignored. The reported
issue was that a pipe was being executed when it was hidden behind a
rem, which was trigged by the preceeding '@' character not being
skipped.

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 's' is used as a modifier, the paths that are presented to the
other modifiers needs to be a short path. Given the 'filename' part of
the path may not exist, we cannot use GetShortPathName directly
without first removing the filename part to just leave the directory
bit.

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.

When parsing a command, after the first '/' we store the characters away
in quals. The command itself can be MAXSTRING in bytes, but the quals was
limited to MAX_PATH. This is incorrect, as you can provide very long
qualifiers as well. Expand the space to allow the maximum size possible.

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
