[patch] mcedit: replace dialog doesn't remember last entered replacement string

[Polynomial-C]

I found this in mc-4.8.12. mc-4.8.11 didn't have this problem.

Edit a file with mcedit and search/replace (F4) a string. Let's say I added "a" as search string and "b" as replacement string. Then I do a couple of replacements with that and exit the dialog (press ESC or Cancel). When re-opening the Replace dialog again, "a" is still in the search string but the replacement string is empty. I expect mc to remember the replacement string as it did in previous versions.

    if ((replace_default == NULL) || (*replace_default == '\0')) 
        replace_default = INPUT_LAST_TEXT;

An empty string is valid for replacement. "Replace by nothing" is useful case.
