Tuomas Tynkkynen	77e9e1ed91	libexpr: Fix prim_replaceStrings() to work on an empty source string ... Otherwise, running e.g. nix-instantiate --eval -E --strict 'builtins.replaceStrings [""] ["X"] "abc"' would just hang in an infinite loop. Found by afl-fuzz. First attempt of this was reverted in e2d71bd186 because it caused another infinite loop, which is fixed now and a test added.	2018-02-26 19:49:13 +02:00
