m4/groff.m4: Search for more shells.
* m4/groff.m4 (GROFF_PROG_SH): A recent message to the Austin Group
mailing list revealed which shells they routinely work with. Search
for shells named ksh93, ksh88, mksh, and yash as well.
"Using the test script in Mantis bug 1915 we have observed four
different behaviors among shells whose behavior we usually consider
when investigating issues: one shared by dash, ksh93 and yash; and one
each from bash, mksh and ksh88."
