 Default style is like normal output. Phases style should be the same
 as default style, except for extra phase lines.
 
   $ hg log > log.out
   $ hg log --style default > style.out
   $ cmp log.out style.out || diff -u log.out style.out
   $ hg log -T phases > phases.out
   $ diff -U 0 log.out phases.out | egrep -v '^---|^\+\+\+|^@@'

   $ hg log --debug --style default > style.out
   $ cmp log.out style.out || diff -u log.out style.out
   $ hg log --debug -T phases > phases.out
   $ cmp log.out phases.out || diff -u log.out phases.out
 
 Default style of working-directory revision should also be the same (but
 date may change while running tests):
 
   $ hg log -r 'wdir()' | sed 's|^date:.*|date:|' > log.out
   $ hg log -r 'wdir()' --style default | sed 's|^date:.*|date:|' > style.out
   $ cmp log.out style.out || diff -u log.out style.out
 
   $ hg log -r 'wdir()' -v | sed 's|^date:.*|date:|' > log.out
   $ hg log -r 'wdir()' -v --style default | sed 's|^date:.*|date:|' > style.out
   $ cmp log.out style.out || diff -u log.out style.out
 
   $ hg log -r 'wdir()' -q > log.out
   $ hg log -r 'wdir()' -q --style default > style.out
   $ cmp log.out style.out || diff -u log.out style.out
 
   $ hg log -r 'wdir()' --debug | sed 's|^date:.*|date:|' > log.out
   $ hg log -r 'wdir()' --debug --style default \
   > | sed 's|^date:.*|date:|' > style.out
   $ cmp log.out style.out || diff -u log.out style.out
 
 Default style should also preserve color information (issue2866):
 
   $ cp $HGRCPATH $HGRCPATH-bak
   $ cat <<EOF >> $HGRCPATH
   > [extensions]
   > color=
   > EOF
 
   $ hg --color=debug log > log.out
   $ hg --color=debug log --style default > style.out
   $ cmp log.out style.out || diff -u log.out style.out
   $ hg --color=debug log -T phases > phases.out
   $ diff -U 0 log.out phases.out | egrep -v '^---|^\+\+\+|^@@'

   $ mv $HGRCPATH-bak $HGRCPATH
 
 Remove commit with empty commit message, so as to not pollute further
 tests.
 
   $ hg --config extensions.strip= strip -q .
 
 Revision with no copies (used to print a traceback):
 
   $ hg tip -v --template '\n'
   
 
 Compact style works:

 Check that recursive reference does not fall into RuntimeError (issue4758):
 
  common mistake:
 
   $ cat << EOF > issue4758
   > changeset = '{changeset}\n'
   > EOF
   $ hg log --style ./issue4758
   abort: recursive reference 'changeset' in template
   [255]
 
  circular reference:
 
   $ cat << EOF > issue4758
   > changeset = '{foo}'
   > foo = '{changeset}'
   > EOF
   $ hg log --style ./issue4758
   abort: recursive reference 'foo' in template
   [255]
 
  buildmap() -> gettemplate(), where no thunk was made:
 
   $ cat << EOF > issue4758
   > changeset = '{files % changeset}\n'
   > EOF
   $ hg log --style ./issue4758
   abort: recursive reference 'changeset' in template
   [255]
 
  not a recursion if a keyword of the same name exists:
 
   $ cat << EOF > issue4758
   > changeset = '{tags % rev}'
   > rev = '{rev} {tag}\n'
   > EOF
   $ hg log --style ./issue4758 -r tip

 Check that {phase} works correctly on parents:
 
   $ cat << EOF > parentphase
   > changeset_debug = '{rev} ({phase}):{parents}\n'
   > parent = ' {rev} ({phase})'
   > EOF
   $ hg phase -r 5 --public

   $ hg log --debug -G --style ./parentphase

 Missing non-standard names give no error (backward compatibility):
 
   $ echo "changeset = '{c}'" > t
   $ hg log --style ./t
 
 Defining non-standard name works:
 
   $ cat <<EOF > t
   > changeset = '{c}'
   > c = q
   > EOF
   $ hg log --style ./t

 Test 'graphwidth' in 'hg log' on various topologies. The key here is that the
 printed graphwidths 3, 5, 7, etc. should all line up in their respective
 columns. We don't care about other aspects of the graph rendering here.

 The point of graphwidth is to allow wrapping that accounts for the space taken
 by the graph.

 Something tricky happens when there are elided nodes; the next drawn row of
 edges can be more than one column wider, but the graph width only increases by
 one column. The remaining columns are added in between the nodes.
