Francois Gouget 040c435075 cmd: Avoid unneeded strlenW() calls.
Neither WCMD_give_help(), nor WCMD_setshow_default() are ever called
with a NULL pointer (notice how WCMD_skip_leading_spaces() already
assumes its argument is not NULL and does not return NULL).

Bernhard Übelacker f238e846e7 cmd.exe: Change parsing of the if command to avoid parsing the operators.
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.

Jason Edmeades 1a7333bec6 cmd: Handle "for" loop handling of tokens, where * does not follow a number.
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.

Jason Edmeades becfbb80b4 cmd: Handle whitespace in 'for' argument items.
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.

Jason Edmeades bc9d68bcbe cmd: Fix 'if exist' with a directory\ as a parameter.
'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 '.'.

Jason Edmeades 8b6ba774c0 cmd: for /f fails to launch quoted program plus args.
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.

Jason Edmeades 58d21b3319 cmd: Handle single line 'if' as nested if or with redirects.
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.

Jason Edmeades 6cb520476a cmd: Fix statements after 'else' inside for loops.
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.

Jason Edmeades 4030a95209 cmd: Handle special case tokens=* in for /f.
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.

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.
