ls-remote accepts versions ending with a dot

[gitburd]

Issue:

nvm ls-remote will not filter versions ending with "."
Resolves issue #983.

Example:

$ nvm ls-remote 5
->       v5.0.0
         v5.1.0
         v5.1.1
         v5.2.0
         v5.3.0
         v5.4.0
         v5.4.1
         v5.5.0
         v5.6.0
         v5.7.0
         v5.7.1
         v5.8.0
         v5.9.0
         v5.9.1
        v5.10.0
        v5.10.1
        v5.11.0
        v5.11.1
        v5.12.0

$ nvm ls-remote 5.
            N/A

After change:

$ nvm ls-remote 5.
->       v5.0.0
         v5.1.0
         v5.1.1
         v5.2.0
         v5.3.0
         v5.4.0
         v5.4.1
         v5.5.0
         v5.6.0
         v5.7.0
         v5.7.1
         v5.8.0
         v5.9.0
         v5.9.1
        v5.10.0
        v5.10.1
        v5.11.0
        v5.11.1
        v5.12.0

Seems great! Can we add a regression test? :-)

[gitburd]

I would love to add a regression test, what is that?

[ljharb]

In this case, in the same way that test/fast/Unit\ tests/nvm\ ls-remote mocks out nvm_ls_remote, a unit test could be added, of nvm_ls_remote, that mocks out nvm_ls_remote_index_tab (with the mock data) in order to exercise this logic.

[ljharb]

To clarify; a "regression test" is a test that would have failed without the PR's fix, but now passes - this prevents a regression, or recurrence, of the bug.

@gitburd is there anything i can help unblock for you on writing a test for this PR? I'd love to get this fix into the next release.

[gitburd]

Sorry for the delay @ljharb I was blocked by being very ill but I can finally start working again. I added a test to test/fast/Unit tests/nvm_ls_remote, could this work?

[ljharb]

Glad you're recovered! This looks great.
