tests: don't match blank output lines as regexes in unified tests

Currently, the following unified test will pass:

  $ echo foo


A blank output line (a line containing just two spaces) will match any
output.

The patch modifies the unified test runner to ignore empty strings
strings when do regular expression matching.

Preparing the subrepository 'sub2'

  $ hg init sub2
  $ echo sub2 > sub2/sub2
  $ hg add -R sub2
  adding sub2/sub2
  $ hg commit -R sub2 -m "sub2 import"

Preparing the 'sub1' repo which depends on the subrepo 'sub2'

  $ hg init sub1
  $ echo sub1 > sub1/sub1
  $ echo "sub2 = ../sub2" > sub1/.hgsub
  $ hg clone sub2 sub1/sub2
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg add -R sub1
  adding sub1/.hgsub
  adding sub1/sub1
  $ hg commit -R sub1 -m "sub1 import"
  committing subrepository sub2

Preparing the 'main' repo which depends on the subrepo 'sub1'

  $ hg init main
  $ echo main > main/main
  $ echo "sub1 = ../sub1" > main/.hgsub
  $ hg clone sub1 main/sub1
  updating to branch default
  pulling subrepo sub2 from .*/sub2
  requesting all changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg add -R main
  adding main/.hgsub
  adding main/main
  $ hg commit -R main -m "main import"
  committing subrepository sub1

Cleaning both repositories, just as a clone -U

  $ hg up -C -R sub2 null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg up -C -R sub1 null
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ hg up -C -R main null
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ rm -rf main/sub1
  $ rm -rf sub1/sub2

Clone main

  $ hg clone main cloned
  updating to branch default
  pulling subrepo sub1 from .*/sub1
  requesting all changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 3 changes to 3 files
  pulling subrepo sub1/sub2 from .*/sub2
  requesting all changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
