News sections not rendered if version is in parentheses

[jayhesselberth]

Rendering NEWS.md with a version in paretheses causes it to be dropped from the rendered page.

If a section begins with this header, it is not present in the rendered page:

# pkgdown (development version)

This renders fine:

# pkgdown 1.3.0.9000

This explains why the development version section is not present on the dev docs

This regex fails to capture parenthetical versions:

pkgdown/R/build-news.R

Line 149 in 59cc923

re <- regexec("^([[:alnum:],\\.]+)\\s+((\\d+[.-]\\d+)(?:[.-]\\d+)*)", titles)

Notably this header renders fine:

# pkgdown 1.3.0.9000 (development version)

but makes for a long section title.

The usethis behavior could be updated to add the dev version before the parentheses.

Same thing also happens if you put a v in front of the version,
For example,

pkgdown v1.3.0.9000

Would cause the news to be dropped on the site. The page is there but no content.

I think we should accommodate these formats:

# pkgdown 1.3.0

# pkgdown v1.3.0

# pkgdown (development version)
