I keep my rc files, including .gitconfig and my default gitignore
list under version control and like to have the same contents
everywhere. Unfortunately my home directory is at different
locations on different systems.
I'd like to be able to put something like this in my ~/.gitconfig:
[core]
excludesfile = ~/.gitignore
or
excludesfile = $HOME/.gitignore
Another idea is to have a non-absolute path be interpreted
relative to the location of .gitconfig, i.e. $HOME, instead of the
current directory. $GIT_DIR/info/excludes is already for
repository-specific excludes so no functionality would be lost.
Below is a sample patch that works for me. We could also use
getpwuid(getuid()) instead of getenv("HOME") to be consistent with
user_path() but this is simpler and arguably more likely what the
user wants when it matters.

Subject: [PATCH] Support "core.excludesfile = ~/.gitignore"
The config variable core.excludesfile is parsed to substitute leading "~/"
with getenv("HOME").
