Regarding Toby's patch:
Probably _is_windows_nt_internal_command() isn't needed or desired. It's more
of a command-line parsing issue, rather than a file-search issue. For example,
CMD will search for an internal name if it's quoted in double quotes in the
command line, such as `"dir" spam`, and where.exe doesn't reserve the names of
CMD's internal functions. If it's kept, note that the following four names are
missing from the nt_internal_commands list: 'BREAK', 'MKLINK', 'VERIFY', 'VOL'.
The patch also makes a couple incorrect assumptions, corrected as follows:
* A filename with an extension will be found and executed
even if the extension is not in PATHEXT.
* The PATHEXT extensions are tried even if a name already
has an extension.
