And even if it was reliable, it doesn't take care of the problem with a 
variable set to N spaces, which is a side-effect of the formatting of 
the Makefile where the variable in question is defined (using \ to span 
lines, and tabs/spaces to separate values of two other variables).  I 
suppose it might be possible to put the \ continuation character 
immediately after the variable preceding it (no space), and use tabs 
only to show leading whitespace in advance of the following variable.  
But then if both variables are set to something, there'd be no divider, 
which would cause its own set of problems.

Something else to consider, too, is that the Makefile rule embeds a 
shell script in a sort of single-line mechanism.  The shell script 
thusly must go through some extra level of parsing, which could wind up 
producing different results from pure-shell-script testing.  For 
instance, enclosing $a in quotes "$a" might not matter in the Makefile, 
as the quotes might disappear as a result of the extra level of parsing.
