when I run
brew update here is the result
[admin@mb125:~/src/test] : brew update Updated Homebrew from 16bd5c86 to 24073dc0. ==> New Formulae mal4s nbimg ==> Updated Formulae aws-elasticbeanstalk boost-bcp ex-vi libxml2 vim youtube-dl
Great there is an updated Vim, let's update it.
[admin@mb125:~/src/test] : brew upgrade vim Error: vim-7.4.052 already installed
so, how do I see what has been updated for Vim and why I can't upgrade it?
