In refpolicy, file_contexts.subs_dist begins with comments:
# This file can is used to configure base path aliases as in:
#
# /aliased_path /original_path_as_configured_in_file_contexts
#
The first line gets parsed in read_file_equiv even though it is not a
valid path substitution and the second line triggers an exception when
accessing f[1]:
IndexError: list index out of range
Parse substitutions only for lines which are not comment.
