[PATCH 01/12] dir.c: rename cryptic 'which' variable to more consistent name

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

From: Adam Spiers <git@adamspiers.org>

'el' is only *slightly* less cryptic, but is already used as the
variable name for a struct exclude_list pointer in numerous other
places, so this reduces the number of cryptic variable names in use by
one :-)
