* misc.c: Removed the sindex() function. All instances of this
function were trivially replaceable by the standard strstr()
function, and that function will always have better (or certainly
no worse) performance than the very simple-minded algorithm
sindex() used. This can matter with complex makefiles.
* make.h: Remove the prototype for sindex().
* function.c (subst_expand): Convert sindex() call to strstr().
This means we no longer need to track the TLEN value so remove that.
(func_findstring): Convert sindex() to strstr().
* commands.c (chop_commands): Convert sindex() calls to strstr().

* main.c (find_and_set_default_shell) [WINDOWS32]: Implement the
idea behind Savannah Patch #3144 from david.baird@homemail.com.
If SHELL is set to CMD.EXE then assume it's batch-mode and
