Summary 0001599: Unspecified behaviour for "strings -" too narrow
Description The strings DESCRIPTION says:
If the first argument is '-', the results are unspecified.

However, many implementations also treat '-' as special when it is not the first argument. They handle it as if it were a -a option, so:

strings -n 1 - file

is equivalent to:

strings -n 1 -a file

On Solaris, macOS, and HP-UX, this includes still recognising options after '-', e.g. for:

strings -n 1 - -t x file

the -t x is recognised as an option. (Whereas GNU, with POSIXLY_CORRECT, reports that files named -t and x were not found.)

GNU, Solaris, and HP-UX also treat an operand of '-' that is not the first argument as special. (For GNU it turns on -a for later files; for Solaris it turns on -a for all files; for HP-UX it is treated as a file named '-a'!)
Desired Action On page 3259 line 109562 section strings, change:
If the first argument is '-', the results are unspecified.
If any argument is '-', the results are unspecified.
