Previously, two underscore characters in a document would mark the entire
space between them as italic, no matter how far apart. Now we only accept a
single consecutive newline within an inline-formatted span, so hard-wrapped
documents will still format nicely but stray characters won't mess up your
entire document.
Note that the highlighter for backtick-enclosed spans was modified,
even though it's redundant with the code-block highlighting introduced
in 5bc62c694.
As well as the traditional `[text](url)` syntax, Markdown allows the text to
be followed by a tag in square brackets. If the text is followed by nothing
at all, then the tag for that link is the text itself. The actual URL
is supplied later in the document, like a footnote at the bottom of the page:
Some text with [a link][tag] and [another link].
[tag]: http://www.example.com/link1
[another link]: http://www.example.com/link2
This adds the "link" face to the URL in such footnote lines.
Reference highlighters allow for potential mutual recursion between
highlighters. This is usually fine, but if the recursion happens on
the same buffer range, it means we will recurse infinitely.
Fixes#1920
Pressing Y or N will set the buffer (or window, if it is set at that
scope) autoreload option to the corresponding value, avoiding infinite
loops where a file getting constantly modified prevents the user from
using Kakoune.
To allow more general look arounds out of the actual search range,
pass a second range (the actual subject). This allows us to remove
various flags such as PrevAvailable or NotBeginOfSubject, which are
now easy to check from the subject range.
Fixes#1902
Change the logic of open line commands so that if a selection lies
on the end of line character of the line from which we open a new
line, that selection does not move.
If we have two clients, A and B, with B's cursor on the eol character
of line L, and A hits `o` while on line L, B's cursor should stay
on the same (logical) line. Previous behaviour would make B's cursor
jump on the newly inserted line.
Selection merging is necessary if we want X to work nicely when we are
on EOL (jumping to next line is as nice as it could be, and we are much
more often on EOL nowadays).
