display: ensure that spotlighted text is not treated as a prompt answer

When doing replacements or fixing misspelled words, and edit_refresh()
is called to highlight the relevant word, then the current menu can be
anything from MREPLACEWITH, MYESNO, MSPELL, or MMAIN.  Make sure it is
always set to the latter just before calling edit_refresh(), so that
display_string() will use the full length and the word gets properly
highlighted.
