Fixes PowerShell square brackets formatting issue

[gabr]

Apparently having square brackets in listing is not possible. I tried different forms of escaping them using \, `, [ and html codes without success. Only switching syntax from listing to the block helped.

tried quotes ?

code: 
  - 0.1 + 0.2
  - 0.1 + 0.2 -eq 0.3
  - "[decimal]0.1 + [decimal]0.2 -eq [decimal]0.3"
  - 0.1d + 0.2d -eq 0.3d
