[issue1518] MQ can't handle empty files - file is silently removed after qpop-qpush

[Benny Bach]

New submission from Benny Bach <benny.bach at gmail.com>:

To reproduce:

  md hg-mq-empty-patch
  hg init
  echo "foo" >> foo.txt
  echo "bar" >> bar.txt
  hg addremove
  hg commit -m "initial import"

Now make a patch:
  
  md subdir
  touch subdir\.dummy
  echo "foo" >> foo.txt
  hg add subdir\.dummy
  hg qnew -f empty-file

hg log -v -r 1   shows:
changeset:   1:4adae60125af
tag:         qtip
tag:         empty-file
tag:         tip
tag:         qbase
user:        Benny Bach <benny.bach at gmail.com>
date:        Thu Feb 19 11:30:18 2009 +0100
files:       foo.txt subdir/.dummy
description:
[mq]: empty-file

Now do qpop-qpush

  hg qpop
  hg qpush

hg log -v -r 1   shows:
changeset:   1:01f6b9742f83
tag:         qtip
tag:         empty-file
tag:         tip
tag:         qbase

date:        Thu Feb 19 11:31:00 2009 +0100
files:       foo.txt
description:
imported patch empty-file

subdir/.dummy was lost!
