Fromatador 0.3.0+ breaks Guard test suite.

[voxik]

I observe following test suite errors in Guard:

$ rspec -rspec_helper -f d spec/lib/guard/dsl_describer_spec.rb 
Run options: include {:focus=>true}

All examples were filtered out; ignoring {:focus=>true}

Randomized with seed 38332

Guard::DslDescriber
  #list
    lists the available Guards declared as strings or symbols (FAILED - 1)
  .notifiers
    properly connects and disconnects
    shows the notifiers and their options (FAILED - 2)
  .show
    shows the Guards and their options

And I'd blame #32 for this, because it makes and assumption that every displayed unicode character occupies two single byte columns. But that is not universal true, as can be seen from this test case leveraging the unicode gem:

$ ruby -runicode -e 'p Unicode.width("✔")'
1

$ ruby -runicode -e 'p Unicode.width("震度")'
4

Me not being Japanese, I'd propose to revert #32, but yeah, not sure how to make everybody happy:

$ ruby -runicode -e 'p Unicode.width("🤷")'
1
