Release knitr 1.50 · yihui/knitr

NEW FEATURES

For inline code expressions, their specific line numbers will be shown in the message when errors occur (thanks, @kevinushey, #2387). Previously, the numbers were not specific to the inline code but the lines of the whole text chunk containing the inline code, which are often quite vague.
Display error traceback when vignettes fail in R CMD build (thanks, @hadley, #2390).
kable() properly supports column alignment for Org Mode tables now (thanks, @mclements, #2391).

Moved implementations of combine_words() and write_bib() to the xfun package as xfun::join_words() and xfun::pkg_bib(), respectively, since they are not directly relevant to knitr. The functions combine_words() and write_bib() are still kept in knitr, and can continue to be used in the future.
A warning will be issued when chunk options are duplicated in both the chunk header and pipe comments (thanks, @cderv, #2386). A chunk option should appear in only one of these places.
Removed the function read_rforge() since it has stopped working for a long time.
Removed demos from the package (which were early experiments from several years ago).
