To reproduce the bug:

1. create a file named "a,1" (without the quotes) in the current directory
2. press the + button to select a group of files
3. enter "a,jklmn 56789" (without the quotes) as selection string

MC selects the file named "a,1".

This is a special case of #2309. "a,jklmn 56789" is translated as two alternatives: "^a" and "jklmn 56789$", the first one matches.
