merge: when --tool is specified, disable HGMERGE by setting to empty string

HGMERGE has different semantics than ui.merge.  HGMERGE should hold the name
on an executable in your path, or an absolute tool path.  As such, it's not
safe to simply copy the user's specified --tool value into HGMERGE.  Instead,
we disable HGMERGE by setting it to an empty string.

create cvs repository

  $ mkdir cvsrepo

Create a new project

  $ mkdir src
  $ cd src
  $ echo "1" > a
  $ echo "1" > b
  $ cvscall import -m "init" src v0 r0 | sort
  $ cd ..
  $ cvscall co src
  cvs checkout: Updating src
  $ cd src

Branch the project

  $ cvscall tag -b BRANCH
  cvs tag: Tagging .
  $ cvscall up -r BRANCH > /dev/null
  cvs update: Updating .

Modify file a, then b, then a 

  $ sleep 1
  $ echo "2" > a
  $ cvscall ci -m "mod a"
  cvs commit: Examining .
  $ echo "2" > b
  $ cvscall ci -m "mod b"
  cvs commit: Examining .
  $ sleep 1
