Thanks. Glancing at the first few hunks, this change didn't seem like a
big cleanup, but then I got to the hunk with all the ugly '\'' bits. :)

The patch looks correct to me (reviewing with "git diff -b" was a big
help).

Hmm.

  $ cd t
  $ git grep ' ()' *.sh  | wc -l
  271
  $ git grep '[^ ]()' *.sh  | wc -l
  247

I'm not sure you are making things any more consistent. But I don't
really care either way.

Just for giggles, I was curious who introduced the styles:

  pattern_authors() {
    git grep -n "$@" |
    while IFS=: read file line match; do
      git blame -L "$line,$line" "$file"
    done |
    perl -lpe '/\((.*?) \d+-\d+-\d+/; $_=$1'
  }

  $ pattern_authors ' ()' t/*.sh | sort | uniq -c | sort -rn
  84 Junio C Hamano
  32 Jonathan Nieder
  16 Thomas Rast
  16 Johan Herland
  12 Johannes Sixt
  12 Johannes Schindelin
  ...

  $ pattern_authors '[^ ]()' t/*.sh | sort | uniq -c | sort -rn
  52 Jeff King
  26 Jonathan Nieder
  18 Nguyễn Thái Ngọc Duy
  16 Wincent Colaiuta
  14 Jon Seymour
  10 Tay Ray Chuan
  ...

So there are definitely particular people who prefer different styles
(and I recalled that Junio and I differed on this style point, which is
confirmed here). Interestingly, you are the only person to fall right in
the middle.  I guess that means you are good at emulating surrounding
code. :)
