Describe the issue

Given this snippet:

<IfModule mod_deflate.c>
 AddOutputFilterByType DEFLATE "application/atom+xml" \
 "application/javascript" \
 "text/xml"
</IfModule>

The line continuation marks ( \) are not recogniezed. Everything following the first line ending with a continuation mark will not be highlighted correctly.

Which language seems to have the issue?
apache aka apacheconf

Are you using highlight or highlightAuto?

highlight="apache" in vue (but can reproduce on vanilla highlightjs)
