simplemerge: avoid quadratic concatenation when building output text
I haven't checked if the difference is measurable, but the new version
is no less readable or idiomatic, so I don't think performance numbers
are needed.

Setup:
$ GIT_AUTHOR_NAME='test'; export GIT_AUTHOR_NAME
> GIT_AUTHOR_EMAIL='test@example.org'; export GIT_AUTHOR_EMAIL
> GIT_AUTHOR_DATE="2007-01-01 00:00:00 +0000"; export GIT_AUTHOR_DATE

> GIT_COMMITTER_EMAIL="$GIT_AUTHOR_EMAIL"; export GIT_COMMITTER_EMAIL
> GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"; export GIT_COMMITTER_DATE
> count=10
> gitcommit() {
> GIT_AUTHOR_DATE="2007-01-01 00:00:$count +0000";
> GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"
> git commit "$@" >/dev/null 2>/dev/null || echo "git commit error"
> count=`expr $count + 1`

$ hg version -v --config extensions.git= | grep '^[E ]'
Enabled extensions:
git internal (pygit2 *) (glob)
Test auto-loading extension works:
$ mkdir nogit
$ cd nogit
$ mkdir .hg
$ echo git >> .hg/requires
$ hg status
abort: repository specified git format in .hg/requires but has no .git directory
[255]
$ git init
Initialized empty Git repository in $TESTTMP/nogit/.git/
$ git config --global init.defaultBranch master
This status invocation shows some hg gunk because we didn't use
`hg init --git`, which fixes up .git/info/exclude for us.
$ hg status
? .hg/cache/git-commits.sqlite
? .hg/cache/git-commits.sqlite-shm
? .hg/cache/git-commits.sqlite-wal
? .hg/requires
$ cd ..
Now globally enable extension for the rest of the test:
$ cat <<EOF >> $HGRCPATH
> [extensions]
> git=
> [git]
> log-index-cache-miss = yes
> EOF
Make a new repo with git:
$ mkdir foo
$ cd foo
$ git init
Initialized empty Git repository in $TESTTMP/foo/.git/
Ignore the .hg directory within git:
$ echo .hg >> .git/info/exclude
$ echo alpha > alpha
$ git add alpha
$ gitcommit -am 'Add alpha'
$ echo beta > beta
$ git add beta
$ gitcommit -am 'Add beta'
$ echo gamma > gamma
$ git status
On branch master
Untracked files:
(use "git add <file>..." to include in what will be committed)
gamma
nothing added to commit but untracked files present (use "git add" to track)
Without creating the .hg, hg status fails:
$ hg status
abort: no repository found in '$TESTTMP/foo' (.hg not found)
[10]
But if you run hg init --git, it works:
$ hg init --git
$ hg id --traceback
heads mismatch, rebuilding dagcache
3d9be8deba43 tip master
$ hg status
? gamma
Log works too:
$ hg log

and bookmarks:
$ hg bookmarks

diff even works transparently in both systems:
