The first one says to match the characters "\textbf{" then one or more
characters in non-greedy mode followed by a "}".  You need the match to
be non-greedy since {.+} on the string "\textfb{junk}\index{more
junk}" would match "junk}\index{more junk", not just "junk".

The second one says to match the characters "\textbf{" then zero or
more characters that are not a "}" followed by a "}".

I suppose that there are subtle differences between the two that
could cause problems in special cases, but both should be functionally
the
same for the most part.  I personally use the second form (you only
have to get burned by a greedy match once to understand why).
