Asciidoc xref links: WikiLinkOpen doesn't open links without hash

[mgoral]

Hi!

According to the help file, wiki.vim now supports these two forms of Asciidoc's inline macros:

xref:anchor[]
xref:file.adoc#anchor[]

However, I wonder if it should also support the first form (without the hash), but leading to another file instead of the anchor in current file:

xref:file.adoc[]

It looks like it is correct Asciidoc's document-to-document cross reference: https://docs.asciidoctor.org/asciidoc/latest/macros/inter-document-xref/#navigating-between-source-files

Currently, if user creates such xref by hand (because WikiLinkOpen automatically creates a version with hash), wiki.vim will do nothing and will print "Can't open link before you've saved the current buffer", which is also a different behaviour than if we had the version with hash (which would allow following the link without saving current buffer).

First, sorry for the extremely slow response!

I've pushed an update that I think fixes a couple of minor issues with adoc links. I also allowed this form as you suggest by matching against the .adoc at the end of the url string. So, for xref:string[], the string will in general be recognized as an anchor pattern, except with string ~= ".adoc$". I believe this should behave as expected in most cases?

...wiki.vim will do nothing and will print "Can't open link before you've saved the current buffer", which is also a different behaviour than if we had the version with hash (which would allow following the link without saving current buffer).

I strongly suggest that you use the set hidden option in Vim (and read the corresponding docs). Learn to navigate between buffers if you have not already done so. It is a very useful feature!
