word_document2 "multiple labels on one line" error #538
Description
I'm encountering an error when trying to render a word_document2 with more than one figure in a single chunk. Both #249 and #483 suggested this issue had been fixed, and should just result in a warning, but I'm getting it with the latest version of bookdown right now.
Sample document:
```{r figs, fig.cap = "Figure caption.", fig.show = "hold"}
plot(iris)
plot(mtcars)
```
Building with bookdown::pdf_document2 works fine. However, I get the following error if trying to use word_document2:
> bookdown::render_book("figures.Rmd", "bookdown::word_document2")
processing file: _main.Rmd
|...................... | 33%
ordinary text without R code
|........................................... | 67%
label: figs (with options)
List of 2
$ fig.cap : chr "Figure caption."
$ fig.show: chr "hold"
|.................................................................| 100%

output file: _main.knit.md
Error in parse_fig_labels(x, global) :
There are multiple labels on one line: (#fig:figs), (#fig:figs)
In addition: Warning messages:
1: In (knit_hooks$get("plot"))(file, reduce_plot_opts(options)) :
The chunk option fig.show="hold" is not supported for Word output
2: In (knit_hooks$get("plot"))(file, reduce_plot_opts(options)) :
Show Traceback
Rerun with Debug
Error in parse_fig_labels(x, global) :
There are multiple labels on one line: (#fig:figs), (#fig:figs) Please delete _main.Rmd after you finish debugging the error.
While I expected the warning about fig.show="hold" for Word, I did not expect the error.
