[llvm] r240973 - Simplify .gitignore: projects/* => projects/*/

[Chris Bieneman]

I see the other thread now.

What if instead we did something like this:

diff --git a/.gitignore b/.gitignore
index f3424d2..e3d191d 100644
--- a/.gitignore
+++ b/.gitignore
@@ -43,7 +43,9 @@ autoconf/autom4te.cache
 # Directories to ignore (do not add trailing '/'s, they skip symlinks).
 #==============================================================================#
 # External projects that are tracked independently.
-projects/*/
+projects/*
+!projects/*.*
+!projects/Makefile
 # Clang, which is tracked independently.
 tools/clang
 # LLDB, which is tracked independently.

It still wouldn’t be perfect, but it is less error-prone since most files other than Makefiles have extensions.

Thoughts?
