v0.11.1 Improved tests by capturing stderr In previous versions, the warnings emitted by acronymsdown were directly printed to the terminal. This messed up the reporter of 'testthat' (which expects to control what is printed or not; warnings were printed between tests lines...). Also, we could not run tests on these warnings. For example, when a key is missing, it is perfectly normal for acronymsdown to print a warning (it is even expected). This version brings a new capture-error behaviour to solve these problems. The capture-error is only enabled if a specific shared library is compiled (the newly introduced dup2_helper). End users do not need to compile this library: it is only useful for testing purposes. Acronymsdown runs will full features without it.
