parse: Handle multiple flags at once like -LEXO2
The POSIX Utility Syntax Guidelines specify that flag groups like -HL should be handled like -H -L. GNU find doesn't support grouping flags in this way, but BSD find does. To avoid conflicts with non-flag primaries, for now we require at least one flag in a group to be a capital letter. That is, we support things like -Lds but not -ds. We also do not support -fPATH (without a space) as it would conflict with -follow, -fprint, etc. It is impossible to be compatible with both GNU and BSD find here: user@gnu$ find -follow link link/file ... user@bsd$ find -follow find: ollow: No such file or directory Link: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap12.html
