Getting rid of the assumption behind _PATH_DEFSHELLDIR (that all shells
live in the same directory) is very appealing. Once you do that, you
can probably rip out the existing DEFSHELL_CUSTOM stuff, letting the new
DEFAULT_SH stuff do the same work instead.
However, I have never understod why make has built-in knowledge of
multiple shells. Why doesn't it just have knowledge of how to drive
"sh", along with knowledge of where to find the local system's idea of
a good version of "sh"? Does anybody actually put ".SHELL: name=ksh"
or ".SHELL: name=csh" in Makefiles, and if so, why can't they start
putting ".SHELL: name=csh path=/wherever/bin/csh foo=bar baz=quux"
