let commands that show changesets use templates.
mechanism is same as hgweb templates.

old show_changeset code is still used for now if no template given,
because it is faster than template code when verbose or debug.

simple template can be given on command line using -t, --template.

example:

  hg log -t '{author|person}\n'

complex template can be put in template map file, given on command line
using --map-file.

we give two example map files:
map-log.compact prints 3 lines of output for every change.
map-log.verbose prints exact same output as default "hg log -v".

map files are searched where user says, then in template path as backup.

example:

  hg log --map-file map-log.compact

defaults can be set in hgrc with ui.logtemplate and ui.logmap.

#!/bin/sh

hg init
touch a
hg add a
hg commit -m "Added a" -d "0 0"

touch main
hg add main
hg commit -m "Added main" -d "0 0"
hg checkout 0

echo Main should be gone
ls

touch side1
hg add side1
hg commit -m "Added side1" -d "0 0"
touch side2
hg add side2
hg commit -m "Added side2" -d "0 0"

hg log

echo Should have two heads, side2 and main
hg heads

echo Should show "a side1 side2"
ls

hg update --debug -C 1
echo Should only show "a main"
ls
