Not all distros have a `realpath` command. Provide a function that uses the real command if available else use the fish builtin. Fixes #2932

# Provide a minimalist realpath implementation to help deal with platforms that may not provide it
|
|
# as a command. If a realpath command is available simply pass all arguments thru to it. If not
|
|
# fallback to alternative solutions.
|
|
|
|
# The following is slightly subtle. The first time `realpath` is invoked this script will be read.
|
|
# If we see that there is an external command by that name we just return. That will cause fish to
|
|
# run the external command. On the other hand, if an external command isn't found we define a
|
|
# function that will provide fallback behavior.
