`/` character not consistently treated

[mazzma12]

$ echo "select/**/*/**/from/**/events;" | sqllexerv2 -mode tokenize -format txt
IDENT WILDCARD WILDCARD MULTILINE_COMMENT IDENT WILDCARD WILDCARD OPERATOR IDENT PUNCTUATION

gives

"IDENT WILDCARD WILDCARD MULTILINE_COMMENT IDENT WILDCARD WILDCARD OPERATOR IDENT PUNCTUATION"

but if we add a space after the select the "/" is correctly detected

$ echo "select /**/*/**/from/**/events;" | sqllexerv2 -format txt -mode tokenize
COMMAND MULTILINE_COMMENT WILDCARD MULTILINE_COMMENT IDENT WILDCARD WILDCARD OPERATOR IDENT PUNCTUATION
