fold: add squash as a possible alias

In order to respect the habituation of the majority of DVCS users and
to make this feature more easily discoverable, the very common
"squash" terminology should be added as a synonym to "fold". Since git
does not have a squash command, this should be safe.

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"

So here we are::

  $ hg book
     feature-A                 1:568a468b60fc
   * feature-B                 2:7b36850622b2


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 - 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

(amend of public changeset denied)

  $ hg phase --public 0 -v
  phase changed for 1 changesets
