If you have relocated your HOMEBREW_CACHE under HOMEBREW_PREFIX,
then don't show these files as "unbrewed".

The new formula debugger users continuations to jump back up the stack,
and thus anything that has the potential to be executed twice (i.e.
ensure blocks) needs to to be essentially idempotent.

Enumerable#one? is not available under Ruby 1.8.6. Further, we really
want #any? here, as setting both HOME and CURL_HOME can trigger a false
negative.

Fixes Homebrew/homebrew#15883.

Having a third-party `fuse.pc` file will conflict with the `fuse4x` formula.

stdenv already works as Contributions/cmds is in the path already.

This is safe to do because OS X already has git and svn in the PATH if you have the CLT installed. So we should definitely ensure we use the right versions.

Cleaned up the patch a little. Still ugly though, but logic is unusual so that's just how it is.

This has to be a last resort right? If all we show is that link (plus preceding un-deletable output) and they don't click it then maybe we should just close the ticket and hope they'll use MacPorts instead.

Skip any entries returned by `Dir["Library/Taps/*"].each` that are not
directories.

A new feature for easing the pain of working with complex formulas, or
formulas for large packages. When running brew in debug mode (-d), if an
exception propagates outside the formula's install method, you now get a menu
which lets you return to the point where the exception was raised and perfom
several useful actions, such as:
- printing a backtrace
- entering IRB to examine the context and test ruby code
- entering the debugger (if ruby-debug is available)
- entering a shell
- ignoring the exception or proceeding with the raise as normal

* Fixed conflict in build.rb.
* Removed old debug handling in Formula.brew.

Added doctor check for .curlrc rather than silently ignoring it (#13836).

Removed test in doctor where it actually curl'd a file. It's enough to warn if the curlrc exists. I understand people want to remove the warnings, but the point in the doctor is to help diagnose and not to be some ramification of your UNIX system.

Set#merge is supposed to return self, and Formula#recursive_requirements
depended on this being true.

To allow

  depends_on :x11 => :optional

and friends to work as expected, make requirements record any tags and
add special handling to the X11Dependency to record both a minimum
version and additional tags.
