The escape is cancelled when almost any other character appears, but I think whitespace seems to have been simply forgotten. The fix is so simple: ``` --- a/win32/win32.c +++ b/win32/win32.c @@ -1739,6 +1739,15 @@ w32_cmdvector(const WCHAR *cmd, char ***vec, UINT cp, rb_encoding *enc) *ptr = 0; done = 1; } + slashes = 0; break; case L'*': ``` https://github.com/ruby/ruby/pull/17943 -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/lists/ruby-core.ml.ruby-lang.org/
