[Message part 1 (text/plain, inline)]

Hi, a recent commit (commit fe9b5e022950d53cb23959b76c240e1da27ff0a5) changed 
the definition of the cmake grammar, now there is a new node argument_list used 
to wrap nodes of type argument. 
This causes the following error:
Error during redisplay: (jit-lock-function 1) signaled (treesit-query-error 
"Structure error at" 19 "((foreach_command ((argument) @font-lock-constant-
face (#match \"\\\\(?:^\\\\(?:I\\\\(?:N\\\\|TEMS\\\\)\\\\|LISTS\\\\|RANGE\\\\|
ZIP_LISTS\\\\)$\\\\)\" @font-lock-constant-face)))) ((if_command ((argument) 
@font-lock-constant-face (#match \"\\\\(?:^\\\\(?:AND\\\\|COMMAND\\\\|DEFINED\
\\\|E\\\\(?:QUAL\\\\|XISTS\\\\)\\\\|GREATER\\\\(?:_EQUAL\\\\)?\\\\|LESS\\\\
(?:_EQUAL\\\\)?\\\\|MATCHES\\\\|NOT\\\\|OR\\\\|PATH_EQUAL\\\\|STR\\\\(?:EQUAL\
\\\|GREATER\\\\(?:_EQUAL\\\\)?\\\\|LESS\\\\(?:_EQUAL\\\\)?\\\\)\\\\|VERSION_\\
\\(?:EQUAL\\\\|GREATER\\\\(?:_EQUAL\\\\)?\\\\|LESS\\\\(?:_EQUAL\\\\)?\\\\)\\\
\)$\\\\)\" @font-lock-constant-face))))" "Debug the query with `treesit-query-
validate'")

The attached patch supports both the old and the new grammar.
Thanks.
Vincenzo
