Subject: runtime(skill): Update syntax file to fix string escapes
X-Git-Tag: v9.1.0767~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cb1d1dcc879cadfe81ca0088b7e7ebbcd92a9ff3;p=thirdparty%2Fvim.git

runtime(skill): Update syntax file to fix string escapes

The syntax script allowed for single backslash escapes like this
"string\""
But did not accommodate for the uncommon case:
"<key>\\"
Let's fix this by also skipping over double backslashes in the
skillString region.

closes: #15832
