Because no flags were set for regex matching, the regex engine was
assuming that the subject string past-the-end matched a end-of-line.
As the subject string already ended with a \n character, the regex
engine processing of the "past-the-end" position would match '^$'
as ^ matched past the existing \n and $ matched the assumed
end-of-line.
Fixes#3799
Ranges specified with a +<length> were inconsistent, with +0 meaning
an empty range, while +1 meant a two character long range (first character
+ the following one). Change that to mean a single character.
Fixes#3479
When a region calls the regex highlighter, it is incorrect to share
the regex cache as it means we can get matches that span multiple
regions.
Fixes#3041
First try to break at a whitespace, if that fails (likely because
that last WORD is too long for the wrapping width), then try to
wrap at a 'word' boundary (on a non alphanumeric character).

This should reduce the number of allocations as the memory allocated
for the thread stack and the saves can be re-used between runs instead
of being cleared every time.
The RegexHighlighter range cache can get pretty big in nested
regions use cases, and maintaining it can become pretty costly,
so if it hits a certain size, just drop it.
Should improve performances in #2454
This should greatly reduce memory usage by only caching matches
for ranges that needs to be highlighted, in the case where multiple
regions are nested, this means only the topmost region needs to parse
and cache the whole buffer, other regions highlighter will only ensure
the lines for the ranges they are called up are cached.
Fixes#2454
This adds a limitation that capture matching on regions only works
if the regions start/end/recurse match is less than 65635 byte long.
With this limitation we can reduce the RegexMatch struct size to 16
bytes instead of 32.
This is still not good enough,but should slightly improve high memory
usage as reported in #2454
Previously, when wrapping lines at word boundaries, we would iterate forwards
for "wrap-width" characters, then iterate backwards until we found a word-break,
which was horribly slow.
Now we record the last word-boundary we saw as we iterate forwards, getting a
result in one pass.
Fixes#2339.
