v0.39.5

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

 To **install** or **update** nvm, you should run the [install script][2]. To do that, you may either download and run the script manually, or use the following cURL or Wget command:
 ```sh

Alpine 3.5 - 3.12 required the package `python2` to build NodeJS, as they are older versions to build. Alpine 3.13+ requires `python3` to successfully build newer NodeJS versions, but you can use `python2` with Alpine 3.13+ if you need to build versions of node supported in Alpine 3.5 - 3.15, you just need to specify what version of NodeJS you need to install in the package install script._
