[bug #56449] job.c (construct_command_argv_internal): Must use shell if '%' character is present in recipe line

[Eli Zaretskii]

Follow-up Comment #11, bug #56449 (project make):

make.

I also mentioned calling a Windows program with the argument of %%.  The
program in this case gets the literal two % characters in its argv[] array.

If you invoke your argv.exe program from cmd.exe prompt with "%%" as a
command-line argument, don't you see the same output as what mingw-make.exe
produced before this change?  That is what I see, and that tells me that the
change is simply wrong, as it makes GNU Make behave like a batch file
processor, which is not what's expected.
