 > else statement and expected an indentation.

 > For example:

 > ifdef FOOBAR
 > 	interesting
 > else
 > 	more interesting
 > endif

 > would, according to check-package, need to become:

 > ifdef FOOBAR
 > 	interesting
 > 	else
 > 	more interesting
 > endif

 > Treat 'else' and 'elif' the same as if-like keywords in the Indent test, but
 > take into account that 'else' is also valid shell, so we need to correctly
 > handle line continuation to prevent complaining about the 'else' in:

 > ifdef FOOBAR
 > 	if true; \
 > 	    ... \
 > 	else \
 > 	    ... \
 > 	fi
 > endif

 > We don't add the 'else' and 'elif' statements to start_conditional, because
 > it would cause incorrect nesting counting in class OverriddenVariable.
