These are fixed. (Second one hadn't to be, as we removed the option
itself from the help's search menu)

Okay, so help menu has one more column and help's search menu has only
one option -- cancel. Adding re-search, made me shift a declaration of
answer_copy to the beginning. I also renamed it to saved_answer (just
like margin_copy was renamed to saved_margin).

For sake of readability of *patch*, got it. I was trying to make patch
look more final.

I have added 2 comments in src/help.c. I think rest are either too
short, self-explanatory or both.

Last time on removing MFINDINHELP from MMOST wrecked all functions at
prompt (like history, jumps to prev/next word, word completion, etc.)
and I forgot to fix them. This time they are fixed.
