In theory, `npx nvmrc` can now be used to validate an `.nvmrc` file that `nvm` will support. Allowances have been made for future extensibility, and aliases may no longer contain a `#`.
Fixes#3336. Closes#2288.

GNU tar doesn't support using the -J flag required to unpack
xz-compressed tarballs when xv isn't installed. Check for this
scenario and fallback to using gzip-compressed tarballs.
Fixes#3034
Path lists in environmental variables often give special meaning to
empty entries (e.g. in PATH or MANPATH). These are represented by
leading or trailing colons, or by doubled colons in the middle of the
list.
Adjust the awk invocation to correctly deal with trailing colons by
printing the separator before every field except the first, and then
printing the final separator that is read from the input - this will
either be a colon or the null string. This preserves leading and
trailing colons in all cases while not adding extra colons in the wrong
place.
Add test to confirm the correct behaviour.
Fixes#3144
Remove the call to `ls` that was used to determine the symlink
destination
Reasoning :
* `od` resolves symlink itself due to the use of `fopen`
* Prevent the behaviour of `od` which will hang if the filename is
empty (i.e. `/sbin/init` missing) as it will be waiting for `stdin`
compared to quitting with error if the file just doesn't exist
Fixes#3006
No need to escape the `/` char in a grep pattern.
This is to fix the below error when using newer grep with `nvm_command_info`
> $ nvm_command_info curl
> grep: warning: stray \ before /
> /usr/bin/curl
This happens with at least GNU grep 3.8 version.
`nvm install` fails with "Binary download failed, trying source" when
- running on Bash;
- errtrace (`set -E`) is enabled;
- an ERR trap uses `exit` to return a non-zero status; and
- /sbin/init doesn't exist.
Resolved by moving `ls -dl /sbin/init` to the following `if` statement.
In this context, returning non-zero isn't an error and the ERR trap
isn't executed.
