[Bug] Incorrect space-surround behaviour with HTML comments

[Alexei Mozaidze]

Bug

When trying to use the following HTML comment custom pair:

{
   "<!--", "-->",
   ft = { "html", "markdown", "vue", "svelte" },
   space = { enable = true },
}

It adds space before the cursor correctly, but after the cursor the space is offset by 1, causing the incorrect behaviour.

Reproduction steps

| is the cursor

1. Type <!--

<!--|-->

2. Press <space>

<!-- |- ->

Hacky solution

You surround the pairs manually with spaces:

{
   "<!-- ", " -->", -- Mind the spaces!
   ft = { "html", "markdown", "vue", "svelte" },
}

The problem with this solution is when you successfully make a spaced comment, the spaces in the pair are treated as part of the pair, which means that pressing <space> twice jumps to the end of the pair, and pressing backspace deletes the entire pair along with the spaces inside.

Should be fixed.

Thanks! Could you also enable space for HTML comments now that it works as intended?

Why not.
