_______________________________________________________
Details:
Literal pattern containing quoted percents (without any operative ones) does
not match any word.
# Expected to return 'foo%bar', but returns nothing.
$(filter foo\%bar,foo%bar)
This happens because after calling 'find_percent' function the string length
can decrease, but pattern matching code for literals uses old value of the
length.
The attached patch also removes a code used to restore whitespaces inside the
first argument as far as arguments are always get freed after calling a
function handler anyway.
