_______________________________________________________
Details:
A macro reference like
$(name:op%=%)
where "op" does not match the start of the content of "name" is
incorrectly expanded.
If the content of "name" contains a TAB, this TAB is replaced
by a SPACE.
Since there is no match, $(name:op%=%) should be identical to
$(name)
Even if there was a match, the TAB should not be replaced.
In other words: Pattern Replacement Macro References are
defined to work in a way that the white space between words
is literally retained.
