Browsing Brazilian Portuguese translation

stdio UI plugin says this for yes/no/always/never prompts.
"%0" is the question the user is being asked to respond to.
"[Y/n/Always/Never]" are options that the user will have to type in
response. Please pick reasonable abbreviations for YES and NO (and
full words for ALWAYS and NEVER) that can be typed easily by the user.
Case of the "Y" and "n" are not important; there is no default option
chosen here, so the user will have to fully type out one of these four
options in response. Be sure to translate the strings "Y", "N",
"Always", and "Never", elsewhere, to match what you enter here! At
runtime, the user's response is compared to those strings without
case sensitivity.
