Ignoring the ".DS_Store" files on OS X
Adding a newline before the source string in the ".bash_profile"

Resolved Issue #197
Silence stderr warning on `nvm uninstall' with no configured alias
Reduce usage of `cd' to avoid issues with shell aliases

Since we run in interactive context the builtin `cd' may have been aliased to
print some additional info when invoked, thus it's safer for us to avoid
parsing the output from subshells which calls it.

For instance in .bash_profile I have the following function to redefine
`cd' such that it will list the destination directory contents:
cd () { builtin cd "$@" && ls -F --color=auto }

Drop invalid -a flag for basename.

basename doesn't accept options in bash. This causes the VERSIONS variable get the 'N/A' value for $ nvm ls command.

From basename man page:
NAME
       basename - strip directory and suffix from filenames

SYNOPSIS
       basename NAME [SUFFIX]
       basename OPTION

DESCRIPTION
       Print NAME with any leading directory components removed.  If specified, also remove a trailing SUFFIX.

       --help display this help and exit

       --version
              output version information and exit



coreutils version used in Linux Mint 14 Nadia.

GNU coreutils 8.12.197-032bb                                               September 2011                                                               BASENAME(1)

No idea if this flag exists on FreeBSD or other unixes (if they use gnu coreutils shouldn't be any problem)
