bug#48246: [PATCH] Prevent unnecessary restarings of ispell program.

[Dmitrii Kuragin]

From: Dmitrii Kuragin <dkuragin@ya.ru>

Fix bug when ispell always restarted when `ispell-program-name` has a
custom value. Function `eq` compares the object identity and not the
object values which causes `eq` always return `nil` for values with the
same value but different identity (address). `equal` compares actual
values.
