 PR bin/52715
 Correct a (relatively harmless) use after free in prompt expansion
 processing [detected by asan.]
 Relatively harmless: as (while incorrect) the way the data is (was)
 used more or less guaranteed that the buffer contents would be
 unaltered until well after they are (were) no longer wanted (this
 is the expanded prompt string, it is just output (or copied into
 libedit internal storage) and forgotten.
 This should make no visible difference to anyone (not using asan or
 similar.)
