hooks: replace if-try-finally with a "with" statement

This seems like a textbook case for the new demandimport.deactivated
context manager: check if something must be done, do it, and cleanup
at the end regardless of exceptions.

The diff isn't as bad as it seems. It's just all the whitespace
changes due to needing an extra level of indentation. It looks cleaner
with `hg diff -w`.

test merge-tools configuration - mostly exercising filemerge.py

  $ unset HGMERGE # make sure HGMERGE doesn't interfere with the test
  $ hg init

revision 0

  $ echo "revision 0" > f
  $ echo "space" >> f
  $ hg commit -Am "revision 0"
  adding f

revision 1

  $ echo "revision 1" > f
  $ echo "space" >> f
  $ hg commit -Am "revision 1"
  $ hg update 0 > /dev/null

revision 2

  $ echo "revision 2" > f
  $ echo "space" >> f
  $ hg commit -Am "revision 2"
  created new head
  $ hg update 0 > /dev/null

revision 3 - simple to merge

  $ echo "revision 3" >> f
  $ hg commit -Am "revision 3"
  created new head

revision 4 - hard to merge

  $ hg update 0 > /dev/null
  $ echo "revision 4" > f

Tool selection

default is internal merge:

  $ beforemerge
  [merge-tools]
  # hg update -C 1

hg merge -r 2
override $PATH to ensure hgmerge not visible; use $PYTHON in case we're
running from a devel copy, not a temp installation

  $ PATH="$BINDIR" $PYTHON "$BINDIR"/hg merge -r 2
  merging f
  warning: conflicts during merge.
  merging f incomplete! (edit conflicts, then use 'hg resolve --mark')
  0 files updated, 0 files merged, 0 files removed, 1 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg update -C .' to abandon

  space
  # hg stat

simplest hgrc using false for merge:

  $ echo "false.whatever=" >> .hg/hgrc
  $ beforemerge

true with higher .priority gets precedence:

unless lowered on command line:

or false set higher on command line:

  # hg update -C 1
  $ hg merge -r 2 --config merge-tools.false.priority=117

  $ aftermerge
  # cat f

and true.executable set to cat with path works:

Merge with "echo mergeresult > $local":

  $ beforemerge

  $ aftermerge
  # cat f

- and $local is the file f:

  $ beforemerge

  false.whatever=

  true.executable=cat
  # hg update -C 1
  $ hg merge -r 2 --config merge-tools.true.executable=echo --config merge-tools.true.args='mergeresult > f'

  (branch merge, don't forget to commit)

  # cat f

Merge with "echo mergeresult > $output" - the variable is a bit magic:

  $ beforemerge

  # hg update -C 1
  $ hg merge -r 2 --config merge-tools.true.executable=echo --config merge-tools.true.args='mergeresult > $output'
