evolve: drop useless return
This return statement is never reached. This a actually a good new because its
variable was undefined. We remove it.

Creating And Updating Changeset
===============================
Setup the Base Repo
-------------------
We start with a plain base repo::
$ hg init main; cd main
$ cat >main-file-1 <<-EOF
> One
>
> Two
>
> Three
> EOF
$ echo Two >main-file-2
$ hg add
adding main-file-1
adding main-file-2
$ hg commit --message base
$ cd ..
and clone this into a new repo where we do our work::
$ hg clone main work
updating to branch default
2 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ cd work
Create First Patch
------------------
To begin with, we just do the changes that will be the initial version of the changeset::
$ echo One >file-from-A
$ sed -i'' -e s/One/Eins/ main-file-1
$ hg add file-from-A
So this is what we would like our changeset to be::
$ hg diff
diff --git a/file-from-A b/file-from-A
new file mode 100644
--- /dev/null
+++ b/file-from-A
@@ -0,0 +1,1 @@
+One
diff --git a/main-file-1 b/main-file-1
--- a/main-file-1
+++ b/main-file-1
@@ -1,1 +1,1 @@
-One
+Eins
To commit it we just - commit it::
$ hg commit --message "a nifty feature"
and place a bookmark so we can easily refer to it again (which we could have done before the commit)::
$ hg book feature-A
Create Second Patch
-------------------
Let's do this again for the second changeset::
$ echo Two >file-from-B
$ sed -i'' -e s/Two/Zwie/ main-file-1
$ hg add file-from-B
Before committing, however, we need to switch to a new bookmark for the second
changeset. Otherwise we would inadvertently move the bookmark for our first changeset.
It is therefore advisable to always set the bookmark before committing::
$ hg book feature-B
$ hg commit --message "another feature (child of $(hg log -r . -T '{node|short}'))"
So here we are::
$ hg book
feature-A 1:568a468b60fc
* feature-B 2:73296a82292a
Fix The Second Patch
--------------------
There's a typo in feature-B. We spelled *Zwie* instead of *Zwei*::
$ hg diff --change tip | grep -F Zwie
+Zwie
Fixing this is very easy. Just change::
$ sed -i'' -e s/Zwie/Zwei/ main-file-1
and **amend**::
$ hg amend
This results in a new single changeset for our amended changeset, and the old
changeset plus the updating changeset are hidden from view by default::
$ hg log
4 feature-B: another feature (child of 568a468b60fc) - test
1 feature-A: a nifty feature - test
0 : base - test
$ hg up feature-A -q
$ hg bookmark -i feature-A
$ sed -i'' -e s/Eins/Un/ main-file-1
