[eric pouech (＠epo)]

it seems to me that the `while (IsCharAlphaNumericA(whichcmd[count]))` loop (above your change) is the culprit

didn't test it, but it's very likely that `for_` `for+` `for.bat` `for.exe` (to name a few) should not be interpreted as `for` command

you should add tests to confirm (or infirm) this assumption and fix the loop accordingly

I wouldn't be surprised if something like (didn't think off all the possible characters)

```
while (strchr(" \t()<>|,=;", whichcmd[count]) == NULL)
```

would be more suited
