+// Regression tests for https://github.com/chriscamicas/abl-tmlanguage/commit/282d6de
+// Before the fix, the include-file "begin" pattern used a single character class
+// (`[\\\/\w$\-\.]+`) for the filename regardless of whether it was quoted, so a
+// space inside a quoted include file name would end the entity.name.include.abl
+// token early, leave the rest of the name/spaces to be re-tokenized as arguments,
+// and make the grammar treat the closing quote as the start of a new (unterminated)
+// string that swallowed the rest of the line, including the closing '}'.
+//
+// The fix splits the pattern into two alternatives: a quoted filename that matches
+// any non-quote character (so spaces are allowed) and an unquoted filename that
+// keeps the original restricted character class.
