[bug #47960] Adding variable assignment and new rule in else, break execution.

[Brian Vandenberg]

Follow-up Comment #1, bug #47960 (project make):

If anything I think it would be best to avoid allowing this sort of thing. 
I'm having trouble reproducing a situation I ran into a year or so ago, but it
looked something like this:


# As you might guess targets.mk has targets in it
include rules/paths.mk rules/tools.mk rules/flags.mk rules/targets.mk

include /a/list/of/makefile/stubs/for/various/projects


... then in one of the makefile stubs:


# some assignments
a=a
b=b
#...
z=z

# vpath stuff
#...

ifeq "something" "${something else}"
# note the tab; my editor decided to be "helpful"
        some valid make statement
#^^^^^^^
# This caused it to associate the line with a recipe that came from
targets.mk
else
# in here there's spaces
        some other valid make statement
endif
