Colouring of prompts is now supported within the shell by prompt escapes.

The consistency and informativeness of + the output of all these arrays has been improved. + - Prompt escapes %x and %I show the source file and line number in + debug prompts (compare %N and %i which show names and line numbers + in the execution environment). + - The option NO_MULTI_FUNCDEF can turn off multiple definition of + functions at once, a rarely used feature that can cause problems + with misplaced "()". + - The "fc" builtin has been enhanced to make non-interactive use possible + and output consistent when the history is manipulated with "print -s". + The completion style accept-exact-dirs has been added.
