New zle_misc.c patch (fixes terminal initialization in putprompt)

[Eskandar Ensafi <esky@xxxxxxxxxxx>]

Hello,

In order for %-sequences to be recognized in prompts (e.g., PROMPT3 in
"select" loops) and "print -P" statements, the terminal escape sequences
must be initialized in noninteractive shells.  The following patch does
exactly this, on demand, when putprompt() is called.

Later,

- Eskandar
